CoVrza /' '■' PREFATORY NOTE THIS volume is intended to mark in some degree its authors' sense of Professor James's memorable services in philosophy and psychology, the vitality he has added to those studies, and the encouragement that has flowed from him to colleagues without number. Early in 1907, at the invitation of Columbia University, he delivered a course of lectures there, and met the members of the philosophical and psychological Departments on several occasions for social discussion. They have an added motive for the present work in the recollections of this visit. Columbia University, March, 19O8.

THE NEW REALISM ESSAYS PHILOSOPHICAL AND PSYCHOLOGICAL THE NEW REALISM By George Stuart Fullerton 1 BEG that it may be understood that no question- begging is intended in my title. A philosophical doctrine is not necessarily worthy of acceptance because it is new. It is foolish to argue that, because a philosophy happens to be the current one, it is deserving of respect; just as it is foolish to argue that, because certain beliefs are discovered to have an affinity with the beliefs current in some by-gone age, therefore they must be antiquated and worthy of rejection. There is no philosophy accepted in our time which has not its roots in the past, and we may always obtain a cheap triumph over its adherents by taunt- ing them with the date at which their ancestors thought that they saw the light. But this is a cheap triumph, indeed, and one which we may all enjoy in our turn. Only he whose reading and reflection have been limited will look upon it as worth enjoying. There are indications that a number of thinkers at the present time are turning their attention to 4 THE NEW REALISM some form of realism — that they have weighed idealism in the balance and have found it wanting. The tendency is, I believe, a growing one, and a number of the leaders of philosophic thought have been drawn into the current. This is, in itself, no reason for assuming that realism is true. In phi- losophy it is not the same thing to be in the right and to be in the fashion, as I have said above. Nevertheless, the fact seems to make a discussion of the comparative merits of idealism and realism the more opportune and the more likely to be of general interest. And it sets one to thinking anew of the great role which realism has played in the past. Not realism in the mediaeval sense of the word, but realism as the modern man understands it; the realism which accepts an external physical world distinct from anyone's ideas, the realism which is in sympathy with the thought of the mass of mankind, the realism which has always been tacitly accepted, I think, by science, ever since there was such a thing as science. We are apt to forget that for very many centuries the world was realistic in its thinking, even those whom we some- times refer to as idealistic philosophers having little in common with those whom we now call idealists — with the men who maintain that there is no ex- istence save psychic existence, and who resolve " things " into the perceptions or ideas of some mind. To this new fashion in thinking it was Descartes who led the way, without seeing what lay at the GEORGE STUART FULLERTON 5 end of his path. He reasoned much as men do now about the function of the bodily senses in bringing us to a knowledge of things ; he shut the mind up to ideas for all its immediate knowledge, and made ideas merely representative of things not themselves directly perceived; he thus placed the world at one remove, and, for his successors, lost the world. Not at once, for old habits of thought persisted, in spite of logic. A world was assumed, even when every connection was cut between it and the knowing mind. But it is hard to go on believing in things when there is clearly no reason at all for so doing. Descartes was the logical forerunner of Berkeley; and in the fulness of time the latter appeared, and in his train the whole tribe of those to whom that self-assertive, that persistent, that seemingly not to be ignored fact, the physical world, became sublimated into a mental thing, or a semi- mental thing, or, at any rate, a thing unlike what mankind had supposed it to be before the advent of the new doctrine. Yet the defection from the old doctrine was not, even when the new one was at the height of its popularity, by any means universal. Those who have held to the pre- Cartesian philosophy, and they have been many, have never bowed down at the new shrine. Doubtless many of them have kept true to their first love out of sheer inertia, as does the traditional Hollander, despising the fickle Italian for his love of change. But to others we may 6 THE NEW REALISM attribute higher motives. And from other quarters protests have been raised, notably from the Scottish philosophers, men of robust good sense, but not always metaphysicians, and sometimes incapable of seeing what the acute idealist may say in his own justification. Moreover, in quiet corners, espe- cially in England and in America, men not directly influenced by Scholasticism have quietly gone on teaching a realistic doctrine in spite of what seemed the dominant note in the philosophy of the time. Furthermore, the man who was not a philosopher, whether he happened to belong among the learned or the unlearned, always believed, as hinted above, in an external world other than the world of ideas, and in his blundering way con- demned the ideahst. With him has stood the man of science, who, whatever he may have said when he attempted to philosophize, consistently has treated physical phenomena in one way and mental phenomena in another. This is a significant distinction, and one not to be conjured out of existence by a mere distribution of titles, by vaguely marked distinctions drawn between philosophy and science, or by the obscurity induced by the cumbersome and highly technical set of phrases, to my mind of doubtful importance, which the idealists from and including Kant have seen fit to call into being. The pendulum now shows unmistakable signs of swinging toward realism. It ought to be under- GEORGE STUART FULLERTON 7 stood that tliis is not an aberration — a phenom- enon to be regarded with concern. It is swinging in the direction of the spontaneous thought of mankind, of the beHef of the ages. Man is natu- rally a realist, though it is undoubtedly true that the uninstructed man is a rather stupid realist. To make of him a reflective and reasonable realist, some natural ability on his part is prerequisite, as is also some labor on the part of his instructor. But, on the other hand, it requires no little effort to turn men into idealists. The doctrine is by no means so satisfactory or so self-evident as it seems to be to those who have become thoroughly in- doctrinated, to whom certain words and phrases have grown to be the most natural expression of their thought and in need of no analysis, who are habituated to an uncomfortable chair, and who no longer find it uncomfortable. But let them think themselves back to the time of their first introduction to philosophy. Did idealism seem natural and reasonable then ? Even the glamour cast by the name — a glamour which has had much to do, I think, with the popularity of the doctrine, can scarcely reconcile a beginner to what seems so little in harmony with good sense and common experience. In so far as any system of reflective thought can be called natural, it is realism that is natural, not idealism. It may be said that, in touching upon certain of the facts brought forward above, I am employ- 8 THE NEW REALISM ing something like an argumentum ad populum. I hope it will be understood that, in so far as I do this, I address only those who make use of a similar argument in favor of idealism. This was shamelessly done by that lovable creature Berkeley, and it has been done repeatedly since. Idealism has been confused with what is ideal, and the appeal has been to the emotions and aspirations of men — an appeal made, of course, in good faith, but a mistaken appeal, for there are all sorts of idealism and all sorts of realism, and either form of doctrine may be inspiring or the reverse. After all, for the philosopher, qua philosopher, the question is : What is the truest account that reflective thought can give of the world in which we find ourselves ? Whether this world is one that pleases us or does not please us is a thing to discuss after we have found out what it really is. In what follows, I shall not rest my case upon an appeal to the authority of great names, whether of the dead or of the living. Nor shall I try to show that realism is a doctrine that ought to attract the pious man or the canny fellow who wants to be on the safe side. I shall not talk of the fashions, nor be contemptuous of those whose sleeves have not the latest cut. I wish to discuss the subject on its own merits : Why should a man, influenced by none other than intellectual considerations, become a realist, and what sort of a realist should he become? GEORGE STUART FULLERTON 9 And, in pursuance of this aim, I shall, first, bring forward what seem to me the deficiencies of idealism as a philosophical doctrine; then, I shall try to show how it happens that men of acute mind have been, and are, misled into embracing it ; finally, I shall endeavor to indicate what ought to be recognized by the man who, in our day, would be a realist. This means, to my mind, that he must not be forgetful of his debt to the idealists, men who have seen a certain truth, even if they have somewhat misconceived it. The limits of this paper compel me to brevity, but such a resume as is here possible may not be without its usefulness. The Deficiencies of Idealism It can scarcely be regarded as without signifi- cance that men generally find themselves com- pelled to distinguish constantly between ideas and "things," and to mark the distinction by using different expressions when they are referring to the one or to the other. Every man w^ould regard it as absurd to talk of a dream image confined within the walls of a real material bottle, of an imagined knife lying upon a real table, of his neighbor's percept — assuming him to know what is meant by the w^ord percept — transfixed and held up to view on the point of a fork. Nor would he find these forms of expression 10 THE NEW REALISM repellent merely because they are unusual. The objection to them is that they stand for ways of treating certain things in his experience which he, in actual practice, repudiates. However dim his distinction between the mental and the material, however incapable he may be of accurately defin- ing things, he has all his life distinguished between the physical and the mental, and the expressions which he spontaneously uses fairly represent this universal and apparently unavoidable distinction. And it cannot be regarded as without significance that this distinction is just as unmistakably rec- ognized by science. There are certain sciences which describe things in space and in time without making the least reference to the mental. It might be claimed by the superficial observer that they take no note of the distinction. But let anyone pass for a moment from the physical to the psychical, and unwarrantably introduce into the material world what properly belongs to a different sphere, and the scientist would be up in arms at once. His real metre is not what seems a metre to this man or to that; his real half-hour is not the interminable time which seems to have elapsed while the weary listener waited for a tiresome paper to be read to its close. He wants no sub- jective ghosts let loose in his world of objective realities, and when he suspects the presence of such, he is restive in the extreme. It may be the direct aim of a science to busy GEORGE STUART FULLERTON U itself only with changes in the external world, and yet it may be compelled incidentally to rec- ognize mental phenomena. Thus, in astronomy, we take into consideration the personal equation, consciously distinguishing between an occurrence in the outer world and the perception of that oc- currence. On the other hand one science, psy- chology, deliberately aims to describe what is carefully distinguished from the physical ; and the kindred disciplines of ethics and sociology base themselves upon similar ground. Imagine the feelings of the psychologist who would be asked to treat the mental phenomena, with which he occupies himself, precisely as he and others are ready to treat physical phenomena ! Neither in the laboratory nor out of it would he have the faintest idea how to undertake such a task. Thus, he who declares all phenomena to be mental repudiates the actual knowledge of the world which both the unlearned and the learned seem to have. He repudiates a distinction which is imbedded in the very structure of human ex- perience. He w^ould introduce confusion into the sciences, if the sciences paid any attention to him, which they do not. Science quietly goes its own way and gives an account of the world of matter and mind as it is revealed to us, or as it is guessed at from indications which are revealed. The man of science who also chooses to be an idealistic philosopher is compelled, as we may see if we will 12 THE NEW REALISM but watch him at his work, to keep his science upon one dish and his philosophy upon another. The latter does not grow out of the former, and it does not conduce to a better understanding of the former. It is irreconcilable with it, and must be kept apart. This appears to have been realized with some clearness by those idealists who have maintained that the realities of science are, after all, but unreal appearances, fitted to command the respect of those only who have not yet at- tained to the beatific vision reserved for the eye of the philosopher. I do not ask anyone to accept a non-mental, material world merely on the ground that such a world is accepted unhesitatingly both in common thought and in science. Nevertheless, I must con- fess that I think that he is a courageous man, an unduly courageous man, who hastily throws it over, merely because he is perplexed to know how to give a good account of it. And when one re- flects that it has been denied, after all, by a mere handful of men, men brought up in and inoculated with the same tradition, men some of whom have been betrayed into extravagances with which even their confreres could feel little sympathy, and, moreover, men struggling with the difl&culties of reflective thought, working in a region in which all results ought to be held tentatively and with some diffidence — when one reflects upon all this, the denial seems the more rash. Of course, the GEORGE STUART FULLERTON 13 few may, on general principles, be admitted to be possibly in the right ; but the assertion that they are in the right ought to be made, if at all, with a good deal of caution. I hardly think it can be called an appeal to autliority to ask that one bear this warning in mind, when one is brought face to face with what seems to be a rather startling philosophical doctrine. But, to come directly to the question itself, what can be said against idealism ? what are the short- comings of the doctrine ? In answering this question, I think we should begin by pointing out that we do not find ourselves in a chaos of experiences. We seem to be in an orderly world, in which the succession of phenom- ena is such that it does not appear to be absurd to speak of "the laws of nature." We recognize phenomena as distributed in space and in time; there is such a thing as history. It is not nonsense to ask where something hap- pened, and when it happened. We turn to a sys- tem, an order, and it is evidently not an arbitrarily constructed system; we try to find the place and the time of some occurrence in question. Any place and any time will not do; sometimes we discover that we have been mistaken, and then we make a correction. Now, it is not every succession of experiences which we have that we call, or have a right to call, a series of phenomena in that order by means of 14 THE NEW REALISM which we date occurrences, or fix the positions, distances, and magnitudes of things. We can and do distinguish perfectly well between subjective changes and objective changes. It may be said that Berkeley, the idealist, rec- ognized in his fashion this same distinction, and expressly referred to the laws of nature, describ- ing them as the orderly ways in which a Divine Spirit arouses ideas in us. But is this account of the matter adequate ? Does it properly mark the distinction between the subjective and the objec- tive ? It is true that we may have a direct expe- rience of objective changes. We may, with the re- lation of our sense-organs to the object unchanged, observe changes taking place in things — we may watch the swelling of a soap-bubble or note the motion of the second-hand of a watch — but the matter is not always so simple. We are constantly changing the position of our body with regard to things ; we open and shut our eyes, thus having experience of things and losing it altogether. And, from a long experience, we have all, whether ideal- ists or realists or not philosophers at all, learned to distinguish between mere changes in sensations and changes in things, between the subjective and the objective. Often the distinction is one suffi- ciently easy to draw ; sometimes we may be puzzled to know what the objective order really is. But in no case is it a fair statement of the matter to suggest that the objective order is simply spread GEORGE STUART FULLERTON 15 out before our gaze, and taken up by us without the labor of discrimination and selection. We are compelled to find out what it is as a whole ; comparatively little is given us directly. It is to a knowledge of this order of phenomena that physical science endeavors to attain. It is position in this order that we try" to determine when we ask regarding the place and time of anything. All our measurements come back to this. When we ask how big an object is, we do not mean to determine how big it looks to this man or that, under these circumstances or under those. We refer to its size relatively to other things in the physical order. And when we ask when some- thing happened, we always refer to this same order. How shall we measure the time which has elapsed since Columbus discovered America ? by physi- cal changes ; by revolutions of the sun. How shall I measure the time which has elapsed since I sat down at this desk to write ? by looking at the clock before me. In certain cases we may be reduced to the poor expedient of falling back upon subjective time — we may be forced to guess how long a time has elapsed by estimating how long the time has seemed. But even here our ultimate reference is to the objective standard. We have had experience of the fact that such seemings may indicate with approximate correctness the hours and half hours marked by the clock. It is because of this that our makeshift is of any service. 16 THE NEW REALISM Our ultimate standard of reference is, then, to the physical world-order; an order of experience, but one not to be confounded with what is sub- jective. Our where and our when, our how great and our how small, our before and our after, our together and our apart, all come back to this. This is the very vertebral column of the organism of experience. It serves to order all phenomena. Reflection makes it evident that we make use of it in the ordering of mental phenomena as well as in the ordering of physical We do not hesitate to speak of mental phenom- ena as coming into existence at this definite time or at that. We never think of anyone as having a thought at no time and in no definite relation to the rest of the system of things. When did Caesar's body cross the Rubicon.^ We measure the time which elapsed between that and any other physical event by a reference to the series of physi- cal changes separating the two. When did Csesar decide to cross ? Surely, we say, during his life- time — on the day of, or on some day preceding, the crossing. The psychologist goes so far as to say: When a certain physical change, of which we at present know little, took place in the man's brain. I shall not here dwell upon the peculiar char- acter of the relation between the decision and the brain-event in question. What the relation is, can, I believe, be made reasonably clear, and I have GEORGE STUART FULLERTON 17 elsewhere essayed the task.^ That which I am here concerned to point out is, that we never at- tempt to date any mental occurrence save in the one way. Without the physical order we are wholly at sea. When did Othello find out that he had grounds for jealousy ? When will Brown make up his mind that it is not wise to speculate in stocks ? When did I have that rosy dream that I had inherited a fortune ? Is there no sense in asking when.^ Men do date mental occurrences. It is done universally. And it is always done in the same way — some point is selected in the suc- cession of physical changes which constitute the objective order, and the mental occurrence in question is referred to that. Moreover, we all distinguish between the minds of Smith, of Jones, and of Robinson. Should the three men, by any chance, happen to have pre- cisely similar sensations, we could never conclude that we were concerned with but the one group of sensations. W^e have to do with three groups ; the sensations of one man may undergo great change; he may turn and walk away from the object at which he has been looking; the other men may stand still and continue to look at the object. Whether the sensations of two men are conceived to be similar or not, our recognition of a plurality of experiences is the same. It is enough for us, that, in the one case, sensations are referred * " Introduction to Philosophy," New York, 1906, chapter ix. 18 THE NEW REALISM to the one body, and, in the other case, are re- ferred to another body. Suppose that I am asked to beheve in a fourth group of sensations, and, when I ask to what body I am to refer them, I am told that they are to be referred to no body. They are not to be con- ceived as the sensations of this man or of that man. They are not the sensations of anyone who has been, is, or shall be anywhere. Can I believe in such a group ? Never ! I can undoubt- edly imagine groups of sensations, or, at any rate, of experiences which, if referred to a body, I should call sensations. But I cannot believe in them as real, so long as they are cut off wholly from the real world of things. They are ab- stractions, mere imaginings. To talk of them as existing is nonsense, unless I mean to indicate by the word only that certain things have a place in my thought, and are actually imagined. Now, suppose that I attempt to be thoroughly idealistic; suppose that I ignore the objective order, as such, and try to order my world solely with reference to ideas properly so called. Where is the room, or the experience of the room, in which I seem to be sitting ? Is it be- tween the idea of a hall and the idea of a garden ? Is there another side to this desk? I am im- agining another side, it is true; but is there any- thing that may be called a space-relation between a percept and a memory- image, as such ? Does GEORGE STUART FULLERTON 19 the other side exist now? or is it a mere poten- tiahty ? Is it in harmony with what we know of desks to say that they are made up of percepts and memory- images ? I wake from sleep, and, looking at my watch, observe that its hands are not in the position in which they were when I last observed it. May I say that I have slept eight hours ? Has time elapsed ? So far as my immediate experience goes, nothing has elapsed. If I have slept soundly, there has been nothing at all between the two ex- periences in question. How shall I date my wak- ing.? Not by referring it to a position among my sensations or ideas. Did anything happen while I slept .'^ Surely. But when did it happen.? Its happening cannot be given a place among my past sensations or ideas. It does not seem more sensible to give it a date in what is present to my imagination after I awake. Such dates we reserve for my thoughts about what happened. Again. I believe that other men live now, and that men lived and died before I was born. I shall not here try to prove the existence of other minds, but shall accept it, as the world, unlettered and lettered, unreflective and philosophic, ideal- istic and realistic, has accepted and does accept it. I shall ask only, how are we forced to speak of these minds if we really ignore the external world, the physical system of things in space and time, the objective order of experience ? 20 THE NEW REALISM We have seen above that it is nonsense to talk of a particular mind which is not particularized by reference to some particular body. May I say that the mind of the Mayor of Philadelphia is to be distinguished from the mind of the Mayor of New York by the fact that the one is referred to a given group of my ideas, and the other to another group ? What is the relation of these two minds to each other when I am not thinking about either of these oflScials ? Do they have real bodies when I am experiencing what Berkeley calls "ideas of sense," and only imaginary bodies when I am experiencing "ideas of imagination"? If we consistently refuse to make any distinction between things and our percepts or images of things, it is not easy to see how we are to escape out of this tangle of absurdities. Furthermore, we all accept the fact that the mind of Francis Bacon came into existence at an earlier date than that of Berkeley. How far apart shall we place the two dates ? Surely, I have no satis- factory scheme of arrangement, if I refer Bacon's mind to my idea of Bacon's body and Berkeley's mind to my idea of Berkeley's body. What are the dates of my ideas ? They have themselves no dates, in any proper sense of the word, if there is no objective order of things distinguishable from ideas. Besides, Bacon and Berkeley lived and died before I had any ideas at all, unless his- tory is to be utterly repudiated. GEORGE STUART FULLERTON 21 It may be maintained that the idealist is not forced to be so complete a subjectivist, pinning his faith to a world into which nothing is admitted save the collections of phenomena which consti- tute finite minds. He may accept a Divine Mind, as did Berkeley, or an Absolute, as have done various other philosophers, and may use it as some sort of a cement to unite the little worlds of finite individual experience which seem in danger of falling into mere chaos unless ordered and related by something distinguishable from themselves. But readers of Berkeley will remember that he gives no indication how a Divine Mind is to be regarded as ordering the experiences of finite minds. He furnishes us with no world-order save that which slips in involuntarily in his recog- nition of the laws of nature, in his half-grasped distinction between ideas of sense and ideas of other classes. In other words, he does not help us except in those moments in which he is in dan- ger of passing over to realism and of admitting an objective order, one not to be confused with what is mental. As for the Absolute, or rather the Absolutes, for they have been many, it remains to inquire how such can serve our purpose. Manifestly, an Absolute that is degraded to the rank of a mere Unknowable can play no part whatever in ordering phenomena. I perceive this desk here; I believe that there is a front- door to this house. What is the relation between the two ? 22 THE NEW REALISM Is one at one point in the Unknowable, and the other at another ? I have a percept at the present moment; I beUeve that Cato had a percept at some time in the past. Is this time which makes me regard my percept and his as not simultaneous measured by a reference to the Unknowable? No man living, unlearned or learned, fixes events in his life by assigning to them dates in the Un- knowable, nor does he determine the location of objects or their distances from one another by having recourse to the same useless nonentity. One may argue that the idealist who accepts an Absolute does not make of it a mere Unknow- able. Yet, so far as the part which it plays in ordering anything or accounting for anything goes, the Bradleyan Absolute, at least, seems quite as useless. We are informed that all exist- ence is psychic existence ; it is assumed that there is a multitude of finite minds or centres of expe- rience; the "Reality" of these finite minds is called the Absolute. But it should be observed that in this Absolute there is no distinction of space or time, quantity or quality, or, indeed, of anything that means anything. Phenomena are not ordered or distinguished from one another by reference to it. No account of anything is rendered more intelligible by bringing it in. What is the relation between successive presentations in my mind, or between presentations in my mind and those in another? GEORGE STUART FULLERTON 23 No answer to such questions can even be at- tempted upon the basis proposed. The real world, both of common life and of science, is simply abandoned. Have I now a percept, and did Cato have one at some time in the past ? this is mere appearance — in Reality there is no time, and, of course, no way of measuring time. How may I distinguish Cato's percept from mine, or, indeed, his centre of experience from my own ? In Reality there is no distinction. It is puzzling to know why the man who wishes to extend or to clarify his knowledge should concern himself with this psychic Unknowable at all. But may not the idealist accept an Absolute that is really of some significance for knowledge ? May he not accept a mind which can, in some intelligible sense, serve as a bond of connection, a basis of orderly arrangement, for phenomena ? What is to prevent one from putting such a mind in place of the external world in which most of us believe ? Why not maintain that the external world, as directly revealed to each of us, is a por- tion of such a mind ? that finite minds are to be regarded either as parts of this inclusive mind, or as related to various bits of it in some way that may fix their relations to each other ? In other words, may one treat an Absolute Mind as science and common sense treat the physi- cal world in space and time, relating this occur- rence and that in the order which it furnishes. 24 THE NEW REALISM referring this mind and that to different bodies in it, and thus fixing the relations of phenomena of all sorts in the universe ? To this I think we have to answer: It is an abuse of the word "mind" to apply it to this system of phenomena. The words "physical" and "mental" are not to be used at random. They have a different connotation. If there is one philosophical truth which seems to have met with general acceptance rather than most others, it is that, in some sense of the words, we have objects in the external world in common^ but are the private proprietors of the mental phenomena which we may experience. Just what this "in common" means, I shall not here inquire; but it does mark a well-recognized distinction between the physical and the mental. We perceive trees and houses ; we infer our neighbor's sensations and ideas. There is, to be sure, a school of thought which maintains that we know other minds directly, and are not shut up to the well-known argument from analogy. But this doctrine sounds plausible only so long as it confines itself to vague phrases such as : " consciousness is social from the be- ginning," etc. ; it breaks down just as soon as one grows explicit. In common life it is as- sumed that we infer the thoughts and feelings of other men and of the brutes from indications gathered from their bodily expressions. In psy- GEORGE STUART FULLERTON 25 chology it would be regarded as absurd to main- tain that we may introspectively scrutinize the consciousness of another as we do scrutinize our own. The great majority of philosophers have accepted this truth frankly; and, as I have indi- cated above, those who have not done so show, when they condescend to particulars and grow definite, that they are forced to acknowledge the truth as w^ell. I perceive the things that my neighbor sees and touches ; his percepts of those things I do not perceive; I merely infer them. This peculiarity of the mental, the fact that it is the property of a given consciousness and is not directly revealed to another, we have no right to deny to an Absolute Mind, if we really are talk- ing about a mind, and have not introduced con- fusion and desolation with the introduction of that unhappy word "absolute." I do not directly perceive the sensations and ideas of the brute; I do not directly perceive those of my fellow-men; there is no reason for maintaining that I directly perceive the mental experiences of any other being, however sublime. But we do have, as has been pointed out, cer- tain direct experiences which we can recognize as those of an objective order of experience, and can distinguish from subjective changes which are taking place in ourselves. I can watch a soap- bubble grow; I can walk toward one which I recognize as remaining of the same size, and can 26 THE NEW REALISM have a whole series of experiences which are ad- mitted by everybody to be series of changing percepts, and not indicative of change in the object. I can destroy a soap-bubble; I can cause it to disappear by closing my eyes. Neither in science nor in common life do we confuse such things. In the one case, we recognize that we have to do with the physical; in the other, that we are concerned with the mental. What right has the philosopher to rub out this distinction ? He has no right. The idealistic philosospher who maintains that the objective order which we are all forced to accept, and of which science attempts to give us an exact account, is an Absolute Mind, has simply recognized the external world and has given it the wrong name. In giving it the wrong name, he may easily be seduced into assigning to it attributes which can properly be assigned only to minds. He may speak of it as good, as blessed, as perfect, etc. When one perceives clearly what one is doing, it is not difficult to see that all this is illegitimate. It is not sensible to say that the external world is happy or is good, just as it is not sensible to say that a percept is in a drawer, that a dream-image is a foot long, or that one's memories of leaden images have a high specific gravity. Such considerations as the foregoing lead me to the conviction that I am not wrong in drawing a sharp distinction between the physical and the GEORGE STUART FULLERTON 27 mental, and in refusing to obliterate that dis- tinction even out of courtesy to an Absolute. We do live in a World. Even in common life we meas- ure things in space, we date events in time, we talk of other minds than our own and refer them to given bodies. A body that exists nowhere and at no time does not exist; a mind which can be referred to nothing means for us only an imagined mind. Science accepts this, and differs from com- mon thought only in being more complete and exact. In other words, we find ourselves in a system of experiences ; and reflection reveals to us that our system would be no system were the physical really left out. Why, then, do men find themselves tempted to be idealists and to ignore the physical as such ? There is certainly some plausible reason, or so many acute minds would not have been impelled to tread a path which leads to conclusions seem- ingly in so little accord with common experience and with good sense. II Why Men become Idealists I have referred earlier in this paper to the verbal confusion and to the emotional influences which may lead some men to embrace idealism. It is not necessary to dwell upon such things here. Men of keen mind are not, as a rule, a slave to the 28 THE NEW REALISM associations which attach to words. I have known only one foreigner who became an iVmerican democrat because of the etymology of the word. And earnest men who are seeking the truth ought to keep their emotions in check, and not sacrifice their logic upon the altar of their desires. I am now concerned only with those who are willing to embrace a philosophical doctrine for no other reason than that it seems to be a reason- able one, or at any rate, a more reasonable one than any rival doctrine presented for their con- sideration. I suppose that what chiefly influences such men to become idealists is that they have a vivid realization of the fact that there is no sense in talking about the external world except as we know something about it, and that we cannot know anything about it unless we have sensations. This is a truth which does not seem to have been suflSciently vivid to the realists of a past age — to the realists who held the ground before idealism became the fashion — though one can find pas- sages enough in their works that bring the truth clearly before the mind of the man who has passed through the schools of the idealists. From a very early time men distinguished between things and the sensations that they arouse in us ; and, not infrequently, men even dwelt upon the possible discrepancy between things as they are and things as they seem to present themselves to our senses. To the Cartesian, the distinction between things GEORGE STUART FULLERTON 29 and our knowledge of them was sharpened, as the body, and the processes which result in perception, became more definitely known. It came to be realized that something must take place in the brain, if a man is to have a sensation. It was ac- cepted that all sorts of things may go on in the outer world, and even in the human body, the man remaining, so long as they are not reported at the little central office, in ignorance of them. From this it seems but a short step to the con- clusion that we have no immediate knowledge of anything but images, representatives of things; that we are directly conscious of mental phenomena only, and must depend for all our knowledge of the physical upon some inference for which a justifi- cation may not unreasonably be demanded. One is moved to assert that our life is passed among images ; that they, at least, are certain and indu- bitable, but that what lies beyond them is some- tliing in which we may believe or disbelieve — is legitimate matter for theoretic doubt. This conclusion is new as well as old; it is, in some quarters, very much in the fashion to-day. Moreover, following the old round, the possibility of doubt first ripens into doubt, and then rots into denial. We are informed that we are shut up for all our knowledge to sensations and to memories of sensations, since we can know only the messages conducted along the nerves to the brain. Then we are told that we have no legitimate reason for 30 THE NEW REALISM even trying to penetrate the darkness which, like a wall, shuts in our sensations. Sensations and their copies are declared to be the property of science; this is land that can be enclosed and cultivated in some rational way. What lies in the meaningless beyond is generously bestowed upon that misguided collector of ciphers, the meta- physician, the poor rich man, whose wealth is purely imaginary. The doctrine has recently elicited some applause. I shall not dwell upon the untenability of this doctrine — upon its getting sensations by invoking the aid of the body, and then denying that there is a body; upon its using the word "sensation" to mark a distinction, and then repudiating the foundation upon which the distinction must be based. That this house is divided against itself must be evident to everyone who gives the matter a little careful attention. Nevertheless, untenable as the doctrine clearly is, it is not equally clear that one may not say a good deal in its behalf. One may be tempted to maintain that, if ever a self- contradictory hypoth- esis deserved a little respect, this one may make a claim to kind treatment. When inspected in itself it is seen to be a suspicious character; yet what appear to be irreproachable witnesses may be summoned to testify in its favor. Thus, common sense recognizes that we can only see things when our eyes are open and feel them GEORGE STUART FULLERTON 31 when we touch them with our bodies. The func- tion of the senses in mediating a knowledge of things is matter of every-day experience. The psychologist describes for us in detail the process by which we came to a knowledge of a world of things, and he founds all our information about the world ultimately upon impressions made upon the periphery of the body and messages con- ducted therefrom to the central nervous system. It is a rash man that will condemn the whole pro- cedure of the science of psychology. And yet, if one accepts it, what then ? If we leave such general considerations and come back to the experience mentioned earlier in this paper as one in which an objective order is revealed, are we not in the same case ? I stand with open eyes and watch the soap-bubble expand. Both the plain man and the man of science would agree with me in maintaining that something is happen- ing in the physical world. But, after all, is there a single experience in the w^iole series revealed to me that may not properly be termed sensation ? If I stood nearer or farther away, I should not see just what I do see. If my eyes were closed, I should not see anything at all. Moreover, I may reflect that, as our experiences of things differ according to the relation of our senses to them, so we have every reason to believe that the experiences of different minds differ. The color-blind man does not see what I see. 32 THE NEW REALISM The experience of the world, if we may call it such, enjoyed by lower creatures in their descend- ing series, probably varies more and more widely from my own. What the world may seem like to possible higher creatures, I may try to guess, but I can be sure of little save that a difference must be expected. Does it not seem true, then, that what the world is perceived to be is a function of the creature experiencing the world ? What more than this is needed to make a man some sort of an ideal- ist.^ For my part, I am tempted to believe that the man who has never felt any leaning toward idealism, notwithstanding the protest of science and of common experience, has never seen very deeply into the constitution of experience. There appear to be so many external worlds, all unlike each other, and each chained to the senses of some perceiving creature. Where, in all this, is the world? Ill The New Realism There is a form of realism sometimes attacked by the idealist, which it is not a difficult task to de- molish, but which, in our day, scarcely seems to have a claim upon powder and shot. He who holds to an external world not revealed in our ex- periences, but existing quite outside of and apart from them, an external world to which no path GEORGE STUART FULLERTON 33 leads, and which cannot be described in any intel- ligible terms, may be permitted to cherish his faith in peace. As he cannot advance what may prop- erly be called an argument, we are under no obli- gation to meet him with what may properly be called an answer. To refute such a realism is not to refute realism. The words "sensation" and "thing," "inner" and "outer," must mark some significant dis- tinction, if they are to be worth disputing about- In the first part of this paper 1 have tried to show that they do mark such a distinction, and that this distinction is one universally recognized, although it is recognized by a few inadvertently and reluc- tantly. In answer to the idealistic contention set forth a little further back, namely, that there is no ex- perience of the world where there is no sensation, I advance, not a denial, but a complementary statement. It is this : There is no sensation, that can he recognized as such, where there is no ex- perience oj the world. What is a sensation ? The word is surely not one to be used at random. No one thinks of employ- ing it as a mere name for anything and everything. When we imagine a tree or a house, we do not admit that we are concerned with sensations. How can we distinguish between sensations and such experiences as these ? But one answer to this question can be given. 3 34 THE NEW REALISM We find in experience an objective order of phe- nomena. No one who has not senses finds it, of course. The phenomena that stand in the objec- tive order are revealed, i. e., they may be referred to the senses of someone, and, in so far, they are his perception of the objective order — the man is rec- ognized as experiencing sensations. But, although we constantly refer phenomena to our senses, this is not our only way of treating them. We relate them to each other directly, abstracting from the relation to sense, and in so far we recognize them as having their place in an objective order. As so considered the phenomena in question are not sensations ; they are qualities of things. That phenomena may have this double relation is evident from the fact that one set of sciences occupies itself with them in the one relation, and another busies itself with them as standing in the other. We can- not repudiate all these sciences. A color merely imagined or seen in a dream cannot be treated by physical science as in any sense the property of a thing; it cannot be regarded by psychology as a sensation. He who dwells upon sense-organs, nerves, and messages, gives a meaning to the word sensation; if he subsequently discards this physiological ap- paratus, or sublimates it into a mere "projection," he ought to discard with it all the meaning he has gained, and ought, in justice, to abandon the use of the word. If, by bad luck, he inconsistently GEORGE STUART FULLERTON 35 holds on to it, he becomes an idealist, a sub- jectivist. Any realism which claims a right to recognition at the present day ought to recognize and to incorporate within itself at least as much truth as has been seen by the subjectivist, and all that may reasonably be deduced from it. What should such a realism admit ? That I shall endeavour to set forth below. 1. First of all, the realist should frankly admit that the only external world about which it can be profitable to talk at all is an external world revealed in experience. At the same time, it is of no little importance to discover what one has, a right to mean by this world revealed in experience. When I say that I perceive a world, I do not mean merely that I am aware of a given group or succession of phenomena of a particular sort. The plain man, the man of science, the philosopher, all recognize the fact that I may speak of perceiving the same tree, whether I perceive it from a distance or near at hand, or whether I am made aware of it through the sense of vision or the sense of touch. Even the idealistic philosopher has dwelt upon this truth — it was Berkeley who pointed out that we speak with propriety when we say that we hear, see, and touch the same coach, although our ex- periences in hearing, seeing, and touching are not identical. The tree is not to be confounded with any one of the experiences that I have ; it may be 36 THE NEW REALISM revealed in any one. If our experiences are con- nected in certain regular ways, as they are, a single experience may represent an indefinitely large group, and may give information regarding it. It is, then, perfectly proper to distinguish between an object in the outer world and any given experience of that object. To draw this distinction, one is in no wise compelled to go be- yond experience, and to lose oneself in the region of the unknown or the unknowable. It is only necessary to realize what the constitution of experience is. 2. When I arrive at a knowledge of other minds, I know that they may not be having the same ex- periences that I am having, and yet I say, without being blamed for saying it, that they perceive the same things. It is not an eccentricity for me to talk thus. I am marking a truth that is generally rec- ognized. The realist should frankly admit that my experiences are not identical with those of my neighbor, and even that they may be very widely different from them. But there is nothing in this to lead him to deny that we both perceive the same tree, or to fall back upon some unknowable and unexperienced tree that no one perceives. He should analyze the situa- tion, and try to discover what the use of the word *'same" indicates in such a connection. It mani- festly does not indicate that we are talking of identical experiences. Everyone knows that they GEORGE STUART FULLERTON 37 are not identical. And yet, we are evidently talking about something that is revealed in experience. What has been said a little above may well be borne in mind here. I have many different ex- periences and yet say that I perceive the same tree ; it is perfectly allowable to distinguish between the one tree and any of the experiences as such. Their differences may be dropped out of sight and emphasis laid upon the function performed by them all, upon the one set of relations in which they all stand. Even so it is possible to abstract from the differences which characterize the experiences of two men, and to speak of the one tree which both perceive. With open eyes and standing at a given distance from a tree, I perceive it ; I also perceive the body of another man, its eyes being directed toward the tree in question ; I infer that he has a perception, as I have. I may stand nearer to the object or further away ; he may stand nearer to it or at a greater distance. Under such circumstances, I must admit that my experiences will vary, and I must believe that his will vary, too. But, if it is legitimate for me to speak of the one tree notwith- standing the variations in my own experiences, it is legitimate for me to use the same words not- withstanding the variations in his. The variations can be set aside ; in fact, they are set aside, and it is recognized that something in the objective order of my experiences serves as a stepping-stone to the 38 THE NEW REALISM experiences of another. Thus we perceive the One World. Science very properly treats it as one, recognizing that the experiences of one man are not cut off from those of another, but belong to the same system with them. What has been dropped out of view is taken up again when we turn to the science of psychology, and ask how the world appears to this individual or to that. 3. Finally, the realist should be quite as ready as anyone else to admit that our knowledge of the world grows and changes ; that we make mis- takes and afterwards correct them; that many things which we now believe to be true about the world, we may later find out to be untrue, and may have to replace with other knowledge. Is such a position compatible with the doctrine that an objective order of phenomena is directly re- vealed in experience ? Surely it is. No philosopher may deny those truths which lie plainly before the eyes of all men, and are im- bedded in the very foundations of common ex- perience and of science. He who would dare to maintain that the world is directly perceived, and that, hence, w^e immediately know the world just as it is, and know all about it, does not merit the com- pliment of a labored refutation. He is already refuted by palpable fact; we learn to know the world gradually, and have to expend upon the process much labor; our common knowledge of nature grows, science grows. He is a desperate GEORGE STUART FULLERTON 39 realist, and blind, indeed, who would undertake to deny such facts. Philosophy should understand and interpret common experience and science, not oppose them with preposterous hypotheses. But, though our knowledge of the world grows, it still remains true that we do learn to know the world, to know not merely my ideas or the ideas of another, but the world — a something contrasted with everyone's ideas. There is found in experi- ence the antithesis of subjective and objective, of inner and outer. What is directly apprehended is but little, yet that little serves as the basis of an imposing structure; were it not given, the struc- ture could not be raised. Moreover, in raising it, we do not build at random. I am not at liberty to piece out the deficiencies of sense-knowledge as it may happen to please me, making for myself any or every kind of a world. To do this is not to learn to know the world; it is, rather, to produce a castle in the air, a phantom which dissolves in the presence of the tests of truth which all men are able, within certain limits, to apply to things. In raising our edifice, we have the foundation of the immediately given, and we have the rules of the inductive and the deductive logic. One may be impatient of waiting for the materials to serve as a foundation; one may generalize hastily or make disjointed deductions ; error is possible, and error of divers sorts. But there is, at least, a theo- 40 THE NEW REALISM retic possibility of attaining to unshakable truth. Even a doubt cannot rest upon nothing; there would be no error, in any sense that has a distinc- tive meaning, were there nothing with which to contrast it. As a matter of fact, we have some- thing with which to contrast it; were it not so, the correction of error would be a meaningless expression. I think it is worth while to dwell upon the truth that it is not well to emphasize excessively the uncertainty or unreality of human knowledge and the ignorance of man. Once, men were fond of doing this in the interests of theological orthodoxy. The scene has shifted, and we find it done now in various quarters in the interests of highly doubtful philosophical speculations. We are told that science is all very well in its own sphere, but that it cannot give us the real truth about things ; or we are warned that the concepts of science are self- contradictory, and will not bear careful scru- tiny. In so far as such statements are not based upon metaphysical considerations which we may well regard with suspicion, they constitute an attack upon that only which lies upon the confines of our knowledge. Molecules, atoms, the ether, and what not, may conceivably be swept into the shadowy realm of exploded beliefs. Nevertheless, our common experience of the worlds of matter and of mind would remain unshaken, and with it a vast number of truths which men have never GEORGE STUART FULLERTON 41 doubted and which men do not doubt. Nor would the accepted methods of the investigation of truth be done away wuth. Men have known for a very long time that it is easier to lift a heavy stone on the end of a lever than it is to raise it in the hands. No criticism of the fundamental concepts of mechanics can suo^wst a doubt here. And it does not sound sensible in such cases to say that our statement regarding the raising of the stone is not really true, but is only a convenient way of ex- pressing something. When we have reason to believe that what we have accepted as accurate statements of truth are either inaccurate or wholly false, we are not left in a mere chaos. We are left with the truth we had before we framed such statements. We must come back to common experience, and start out once more upon the toilsome road of observation and inference. Never are we without a world ; we have discovered merely that we do not know quite so much about the world as we supposed we did. There is, thus, nothing to prevent a man from being a modern realist, and, at the same time, from distinguishing between the world as it is, and the particular stage in the knowledge of the world at which we may seem to have arrived. But, in using the phrase "the world as it is," one must talk sense. He who understands it to mean some sort of an Unknowable must laugh at the efforts of 42 THE NEW REALISM science to attain to truth. On the other hand, he who is carried away by his recognition of the fact that observation is not introspection, of the fact that we do have at times a direct experience of the objective order of phenomena, and who, on this inadequate basis, is betrayed into claiming that " the world as it is," is directly revealed in its ful- ness to the mind of man, is plainly guilty of ex- travagance. Did we know the world thus, there would be no disputes, no correction of errors, no growth in knowledge. "The world as it is" is the goal of our en- deavors. We start with some ground beneath our feet, and we have an approved method of procedure. That progress has been made ought to be admitted even by the most pessimistic. The history of science is not a mere list of revolutions, a series of unstable attempts at government suc- ceeded in each case by a reign of terror. Were it no better than this, men would have been dis- couraged long ago. Some truths have been established ; and there is not now, as there has never been, ground for universal doubt, not- withstanding the rejection of many cherished hypotheses. IV Is this Realism ? I fancy it will seem to some that a realism that admits as much as is admitted in the preceding GEORGE STUART FULLERTON 43 section can scarcely be called a realism at all. It distinguishes carefully, it is true, between the subjective and the objective; and refuses, appar- ently quite in harmony with common sense and science, to call what is revealed as belonging to the objective order mental. It insists that the world should not be confused with anyone's sensations and ideas. But, after all, does it not admit that the world is revealed in phenomena of some sort, and that these phenomena are not independent of the bodily senses ^ Is not "the world as it is" simply a full and accurate account of the world in terms of such phenomena ? ^Yhat, then, shall we say about "the world as it was," before the senses of man and such creatures as man were developed ? Did objects exist as we describe them? It should be borne in mind that science does not hesitate to give, with reservations, an account of the state of the world as it was before man and his senses came into being. Whatever objection the man of science may bring against any such account, it is not that it is couched in terms in- telligible to man. His objection is always that the account in question may not be a good one of its kind. But may we not raise the question which he appears to pass over as not worth raising? May we not ask : Were there objects in exist- ence, as described ? The xeiy stuff which enters into their composition appears to be of compara- 44 THE NEW REALISM lively modern manufacture ; how could they have existed ? Of course, one may raise a somewhat similar question regarding those physical things which we do not actually perceive at any given moment. Does the other side of the moon exist? The words mean nothing except as we bring in the objective order of phenomena revealed in expe- rience, accepting a here and a there, a system of things in space. And when I ask: What was the world like before man and his senses came into being ? my question is wholly without significance unless I accept a system of things in time. In asking the question I have tacitly assumed that it is not mere noise to pronounce the word "before." In other words, I have done exactly what is done by the plain man and the man of science — I have accepted the objective order of phenomena, the external world ; but have found myself puzzled by the fact that this order is, in the case in question, expressed in certain terms. We have seen, how- ever, that it is by no means necessary that it should be expressed in a particular set of terms. This is matter of common experience. I may perceive by sight a series of changes which are to me a revelation of the objective order; I may perceive such by touch ; I may credit my neighbor with ex- periences of the objective order different from my own; I may guess at the experiences of lower GEORGE STUART FULLERTON 45 creatures. Nevertheless, I talk of the one world; I am concerned with the one system ; I may over- look the particular form of the revelation, as it is overlooked, without disastrous results, in common life and in science. When I ask whether this or that external thing exists, I am not concerned primarily with my see- ing it or with my feeling it, or with the fact that some other creature may be percipient of it under some given form. I am concerned with the ques- tion whether it is to he given a place in the objective order. There must, of course, be evidence that things are to be assigned such a place, but the evidence may be of many kinds. Things w4iich are perceived, things which are not perceived, things present, things past and gone, may have such a place. This is what men have always meant by external existence, and what they have instinctively distinguished from mere perception. No philosopher can claim to have discovered this truth; it has always been known, although men embarrassed with the difficulties of reflection sometimes misconceive it. Hence, the man of science is entirely in the right in trying to give us an account of the past in terms of our experience, and in being content with that. If his account is perfect in its kind, it is as true an account as can be given. To ask for more is to make a preposterous demand. He who gives such an account is a realist; and tlie 46 THE NEW REALISM philosopher who approves of his procedure is a reahst, too. Still, it may be insisted, is it not a strange and unnatural doctrine that the world as described by the geologist really existed as described, when it is admitted that the terms of the description must be recognized as related to the senses of man? What actually existed and functioned in the external world before there were sensations of color, of touch and movement, and all the rest ? He who keeps coming back to this has missed the force of what has been said just above. He finds it impossible to grasp what is meant by the word "existence," as it is universally used in speaking of physical things. No man of sense, in common life, would repudiate the revelations of geology, and say that it is a better description of what existed in past ages to call it the unknow- able and the indescribable. No man of science would dream of doing this. Science concerns itself with phenomena and their relations, and we have no science — we have no knowledge — so long as we remain in the realm of the unin- telligible. Nothing is natural save nature, and we know just so much of nature as is revealed to us in the phenomena of the objective and the sub- jective orders. It is not unnatural to maintain that phenomena may have a place in the objective order, and may be said to exist, merely on that account, and without any reference to their place GEORGE STUART FULLERTON 47 in the subjective order. Nor will the doctrine seem stran«:e to one who has learned to distin- guish clearly between the subjective and the ob- jective. He who has not yet learned to do this will say that the geologist "projects" his sensations into the past, and will overlook the fact that, upon his hypothesis, there is nothing that can properly be called past. One more point I must dwell upon before bringing this paper to a close. In speaking of "the new realism," I have not meant to defend just one particular type of doctrine, but rather to point out what must be admitted by any form of realism which would not fly in the face of certain rather palpable facts. I have not dwelt, in the above, upon what I may call the intimate structure of experience. To my mind, the phenomena of the two orders dis- cussed, and the relations which obtain between them, are all that we are called upon to take into account. But there are those who think they find, or must assume, in experience, something very different from phenomena and their rela- tions. They may distinguish between the phenom- ena of which we are aware and the "awareness," co-ordinating the latter with the former; they may claim that there can be no experience except as we admit a "uniting" activity which knits phe- nomena into one whole; they may hold that the "self" is not to be resolved into any collocation 48 THE NEW REALISM of phenomena, but is something wholly different, and something the functioning of which must be taken into account in every discussion of our knowledge. Those who are familiar with the history of speculative thought will realize that we are here brought face to face with a tendency which has assumed varying forms, and is strongly marked in minds of a certain type, or in those which have been subjected to certain influences. I have no intention of combating any of these types of doctrine here. What I wish to do is to point out that there is nothing to prevent their adherents from embracing a realistic doctrine of the sort indicated above. Why may they not dis- tinguish clearly between the phenomena of the objective order and those of the subjective order ? Why may they not recognize that, when we refer phenomena to the former, we do not necessarily mean that anyone is perceiving them ? Such men are usually idealists, but they are not compelled to involve themselves in the difficulties which fol- low in the train of idealism. If it is possible for a man to be a realist while admitting that the geologist's account of past ages is couched in terms of our present experience, why may they not admit that the physical world existed at a time when the "awareness," or the "uniting activity," or the "self," did not exist? They have only to distinguish clearly between the objective order itself and their assumed non- phenomenal GEORGE STUART FULLERTON 49 entity, and to use that order as a framework for the ordering of experience as a whole. If they do this, they are doing what is done in common life and in science — they are distinguishing be- tween the existence of things and our perception of them. Without this distinction we should, indeed, find it hard to get on. DOES REALITY POSSESS PRACTICAL CHARACTER? DOES REALITY POSSESS PRACTICAL CHARACTER ? By John Dewey I IXECENTLY I have had an experience which, insignificant in itself, seems to mean something as an index-figure of the present philosophic situa- tion. In a criticism of the neo- Kantian concep- tion that a priori functions of thought are necessary to constitute knowledge, it became relevant to deny its underlying postulate: viz., the existence of anything properly called mental states or subjective impressions precedent to all objective recognitions, and requiring accordingly some transcendental function to order them into a world of stable and consistent reference. It was argued that such so-called original mental data are in truth turning points of the readjustment, or making over, through a state of incompatibility and shock, of objective affairs. This doctrine was met by the cry of "subjectivism"! It had seemed to its author to be a criticism, on grounds at once naturalistic and ethical, of the ground proposition of subjec- tivism. Why this diversity of interpretations ? So 53 54 REALITY AS PRACTICAL far as the ^Titer can judge, it is due to the fact that certain things characteristic of practical Hfe, such things as lack and need, conflict and clash, desire and effort, loss and satisfaction, had been frankly referred to reality ; and to the further fact that the function and structure of knowing were systematically connected with these practical fea- tures. These conceptions are doubtless radical enough ; the latter was perhaps more or less revo- lutionary. The probability, the antecedent prob- ability, was that hostile critics would have easy work in pointing out specific errors of fact and interpretation. But no: the simpler, the more effective method, was to dismiss the whole thing as anarchic subjectivism. This was and remains food for thought. I have been able to find but one explanation: In current philosophy, everything of a practical nature is regarded as "merely" personal, and the "merely" has the force of denying legitimate standing in the court of cosmic jurisdiction. This conception seems to me the great and the ignored assumption in contemporary philosophy: many who might shrink from the doctrine if expressly formulated hang desperately to its implications. Yet surely as an underlying assumption, it is sheer prejudice, a culture-survival. If we suppose the traditions of philosophic discussion wiped out and philosophy starting afresh from the most active tendencies of to-day, — those striving in social life. JOHN DE^VEY 55 in science, in literature, and art, — one can hardly imagine any philosophic view springing up and gaining credence, which did not give large place, in its scheme of things, to the practical and personal, and to them without employing disparaging terms, such as phenomenal, merely subjective, and so on. Why, putting it mildly, should what gives tragedy, comedy, and poignancy to life, be excluded from things ? Doubtless, what we call life, what we take to be genuinely vital, is not all of things, but it is a part of things ; and is that part which counts most with the philosopher — unless he has quite parted with his ancient dignity of lover of wisdom. What becomes of philosophy so far as humane and liberal interests are concerned, if, in an age when the person and the personal loom large in politics, industry, religion, art, and science, it con- tents itself with this parrot cry of phenomenalism, whenever the personal comes into view ? When science is carried by the idea of evolution into introducing into the world the principles of initia- tive, variation, struggle, and selection ; and when social forces have driven into bankruptcy abso- lutistic and static dogmas as authorities for the conduct of life, it is trifling for philosophy to de- cline to look the situation in the face. The relega- tion, as matter of course, of need, of stress and strain, strife and satisfaction, to the merely per- sonal and the merely personal to the limbo of something which is neither flesh, fowl, nor good 56 REALITY AS PRACTICAL red herring, seems the thoughtless rehearsal of ancestral prejudice. When we get beyond the echoing of tradition, the sticking point seems to be the relation of knowledge to the practical function of things. Let reality be in itself as "practical" as you please, but let not this practical character lay profane hands on the ark of truth. Every new mode of interpreting life — every new gospel — is met with the charge of antinomianism. An im- agination bound by custom apprehends the restric- tions that are relaxed and the checks that are removed, but not the inevitable responsibilities and tests that the new idea brings in. And so the conception that knowledge makes a difference in and to things looks licentious to those who fail to see that the necessity of doing well this busi- ness, of making the right difference puts intelli- gence under bonds it never yet has known : most of all in philosophy, the most gayly irresponsible of the procedures, and the most irresponsively sullen, of the historic fruits of intelligence. Why should the idea that knowledge makes a difference to and in things be antecedently objectionable ? If one is already committed to a belief that Reality is neatly and finally tied up in a packet without loose ends, unfinished issues or new departures, one would object to knowledge making a difference just as one would object to any other impertinent obtruder. But if JOHN DEWEY 57 one believes that the world itself is in transforma- tion, why should the notion that knowledge is the most important mode of its modification and the only organ of its guidance be a priori obnoxious ? There is, I think, no answer save that the theory of knowledge has been systematically built up on the notion of a static universe, so that even those who are perfectly free in accepting the lessons of physics and biology concerning moving energy and evolution, and of history concerning the constant transformation of man's affairs (science included), retain an unquestioning belief in a theory of knowledge which is out of any possible harmony with their own theor}' of the matters to be known. Modern epistemology, having created the idea that the way to frame right conceptions is to analyze knowledge, has strengthened this view. For it at once leads to the view that realities must themselves have a theoretic and intellectual complexion — not a practical one. This view is naturally congenial to idealists ; but that realists should so readily play into the hands of idealists by asserting what, on the basis of a formal theory of knowledge, realities must be, instead of accept- ing the guidance of things in divining what knowl- edge 15, is an anomaly so striking as to support the view that the notion of static reality has taken its last stand in ideas about knowledge. Take, for example, the most striking, because the ex- treme case — knowledge of a past event. It is 58 REALITY AS PRACTICAL absurd to suppose that knowledge makes a differ- ence to the final or appropriate content of knowl- edge: to the subject-matter which fulfils the requirements of knowing. In this case, it would get in its own way and trip itself up in endless regress. But it seems the very superstition of intellectualism to suppose that this fact about knowledge can decide what is the nature of that reference to the past which when rightly made is final. No doctrine about knowledge can hinder the belief — if there be sufficient specific evidence for it — that what we know as past may be something which has irretrievably undergone just the differ- ence which knowledge makes. Now arguments against pragmatism — by which I mean the doctrine that reality possesses practical character and that this character is most effica- ciously expressed in the function of intelligence ^ — seem to fall blandly into this fallacy. They assume that to hold that knowledge makes a difference in existences is equivalent to holding that it makes a difference in the object to he known, thus defeating its own purpose ; witless that the reality which is the appropriate object of knowledge in a given case ^ This definition, in the present state of discussion, is an arbitrary or per- eonal one. The text does not mean that " pragmatism " is currently used exclusively in this sense; obviously there are other senses. It does not mean it is the sense in which it ought to be used. I have no wish to legislate either for language or for philosophy. But it marks the sense in which it is used in this paper; and the pragmatic movement is still so loose and variable that I judge one has a right to fix his own meaning, provided he serves notice and adheres to it. JOHN DEWTEY 59 may be precisely a reality in which knowing has succeeded in making the needed difference. This question is not one to be settled by manipulation of the concept of knowledge, nor by dialectic discussion of its essence or nature. It is a question of facts, a question of what knowing exists as in the scheme of existence. If things undergo change without thereby ceasing to be real, there can be no formal bar to knowing being one specific kind of change in things, nor to its test being found in the successful carrying into effect of the kind of change intended. If knowing be a change in a reality, then the more knowing reveals this change, the more transparent, the more adequate, it is. And if all existences are in transition, then the knowl- edge which treats them as if they were something of which knowledge is a kodak fixation is just the kind of knowledge which refracts and perverts them. And by the same token a knowing which actively participates in a change in the way to effect it in the needed fashion would be the type of knowing which is valid. If reality be itself in transition — and this doctrine originated not with the objectionable pragmatist but with the physicist and naturalist and moral historian — then the doctrine that knowledge is reality making a particular and specified sort of change in itself seems to have the best chance at maintaining a theory of knowing which itself is in wholesome touch with the genuine and valid. 60 REALITY AS PRACTICAL II If the ground be cleared of a priori objections, and if it be evident that pragmatism cannot be disposed of by any formal or dialectic manipu- lations of "knowledge" or "truth," but only by showing that some specific things are not of the sort claimed, we may consider some common sense affiliations of pragmatism. Common sense regards intelligence as having a purpose and knowledge as amounting to something. I once heard a physicist, quite innocent of the pragmatic controversy, remark that the knowledge of a mechanic or farmer was what the Yankee calls gumption — acknowledgment of things in their belongings and uses, and that to his mind natural science was only gumption on a larger scale: the convenient cata- loguing and arranging of a whole lot of things with reference to their most efficacious services. Popu- larly, good judgment is judgment as to the relative values of things : good sense is horse sense, ability to take hold of things right end up, to fit an instru- ment to an obstacle, to select resources apt for a task. To be reasonable is to recognize things in their offices as obstacles and as resources. Intelli- gence, in its ordinary use, is a practical term ; ability to size up matters with respect to the needs and possibilities of the various situations in which one is called to do something; capacity to en- JOHN DE^YEY 61 visage things in terms of the adjustments and adaptations they make possible or hinder. Our objective test of the presence or absence of inteUi- gence is influence upon behavior. No capacity to make adjustments means no inteUigence; con- duct evincing management of complex and novel conditions means a high degree of reason. Such conditions at least suggest that a reality- to-be- known, a reality which is the appropriate subject- matter of knowledge is reality-of-use-and-in-use, direct or indirect, and that a reality which is not in any sort of use, or bearing upon use, may go hang, so far as knowledge is concerned. No one, I suppose, would deny that all knowl- edge issues in some action which changes things to some extent — be the action only a more delib- erate maintenance of a course of conduct already instinctively entered upon. When I see a sign on the street corner I can turn or go on, knowing what I am about. The perceptions of the scientist need have no such overt or "utihtarian" uses, but surely after them he behaves difterently, as an inquirer if in no other way; and the cumu- lative effect of such changes finally modifies the overt action of the ordinary man. That knowing, after the event, makes a difference of this sort, few I suppose would deny : if that were all pragmatism means, it would perhaps be accepted as a harmless truism. But there is a further question of fact: just how is the "consequent" action related to 62 REALITY AS PRACTICAL the "precedent" knowledge? When is "after the event"? What degree of continuity exists? Is the difference between knowing and acting intelli- gently one of kind or simply one of dominant quality ? How does a thing, if it is not already in change in the knowing, manage to issue at its term in action ? Moreover, do not the changes actively effected constitute the whole import of the knowl- edge, and hence its final measure and test of validity ? If it merely happens that knowing when it is done with passes into some action, by what miracle is the subsequent action so pat to the situation? Is it not rather true that the "knowl- edge" is instituted and framed in anticipation of the consequent issue, and, in the degree in which it is wise and prudent, is held open to revision during it? Certainly the moralist (one might quote, for example, Goethe, Carlyle, and Mazzini) and the common man often agree that full knowl- edge, adequate assurance, of reality is found only in the issue which fulfils ideas ; that we have to do a doctrine to know its truth; otherwise it is only dogma or doctrinaire *programme. Experi- mental science is a recognition that no idea is entitled to be termed knowledge till it has passed into such overt manipulation of physical conditions as constructs the object to which the idea refers. If one could get rid of his traditional logical theories and set to work afresh to frame a theory of knowledge on the basis of the procedure of the JOHN DE\\:EY 63 common man, the moralist and the experimentalist, would it be the forced or the natural procedure to say that the realities which we know, which we are sure of, are precisely those realities that have taken shape in and through the procedures of knowing ? I turn to another type of consideration. Cer- tainly one of the most genuine problems of modern life is the reconciliation of the scientific view of the universe with the claims of the moral life. Are judgments in terms of the redistribution of matter in motion (or some other closed formula) alone valid ? Or are accounts of the universe in terms of possibility and desirability, of initiative and responsibility, also valid ? There is no oc- casion to expatiate on the importance of the moral life, nor upon the supreme importance of intelligence within the moral life. But there does seem to be occasion for asking how moral judg- ments — judgments of the would and should — re- late themselves to the world of scientific knowledge. To frame a theory of knowledge which makes it necessary to deny the validity of moral ideas, or else to refer them to some other and separate kind of universe from that of common sense and science, is both provincial and arbitrary. The pragmatist has at least tried to face, and not to dodge, the question of how it is that moral and scientific "knowledge" can both hold of one and the same world. And whatever the difficulties in his proffered solution, the conception that scientific 64 REALITY AS PRACTICAL judgments are to be assimilated to moral is closer to common sense than is the theory that validity is to be denied of moral judgments because they do not square with a preconceived theory of the nature of the world to which scientific judgments must refer. And all moral judgments are about changes to be made. Ill I turn to one aflBliation of the pragmatic theory with the results of recent science. The necessity for the occurrence of an event in the way of knowl- edge, of an organism which reacts or behaves in a specific way, would seem to be as well established as any scientific proposition. It is a peculiar fact, a fact fit to stir curiosity, that the rational function seems to be intercalated in a scheme of practical adjustments. The parts and members of the organism are certainly not there primarily for pure intellection or for theoretic contempla- tion. The brain, the last physical organ of thought, is a part of the same practical machinery for bringing about adaptation of the environment to the life requirements of the organism, to which belong legs and hand and eye. That the brain frees organic behavior from complete servitude to im- mediate physical conditions, that it makes possible the liberation of energy for remote and ever ex- panding ends is, indeed, a precious fact, but not JOHN DEWEY 65 one which removes the brain from the category of organic devices of behavior/ That the organ of thinking, of knowledge, was at least originally an organ of conduct, few, I imagine, will deny. And even if we try to believe that the cognitive function has supervened as a different operation, it is difficult to believe that the transfiguration has been so radical that knowing has lost all traces of its connection with vital impulse. But unless we so assume, have we any alternatives except to hold that this continual presence of vital impulse is a disturbing and refracting factor which forever prevents knowledge from reaching its own aim; or else that a certain promoting, a certain carrying forward of the vital impulse, importing cer- tain differences in things, i^ the aim of knowledge ? The problem cannot be evaded — save ostrich wise — by saying that such considerations are "merely genetic," or "psychological," having to do only with the origin and natural history of knowing. For the point is that the organic reac- tion, the behavior of the organism, affects the content of awareness. The subject-matter of all awareness is thing-related- to-organism — related as stimulus direct or indirect or as material of response, present or remote, ulterior or achieved. ' It is interesting to note how the metaphysical puzzles regarding " paral- lelism," "interaction," "automatism," the relation of "consciousness" to "body," evaporate when one ceases isolating the brain into a peculiar physical substrate of mind at large, and treats it simply as one portion of the body as the instrumentality of adaptive behavior. 5 66 REALITY AS PRACTICAL No one — so far as I know — denies this with re- spect to the perceptual field of awareness. Pains, pleasures, hunger, and thirst, all "secondary" qualities, involve inextricably the "interaction" of organism and environment. The perceptual field is distributed and arranged as the possible field of selective reactions of the organism at its centre. Up and down, far and near, before and behind, right and left, hard and soft (as well as white and black, bass and alto), involve reference to a centre of behavior. This material has so long been the stock in trade of both idealistic arguments and proclamations of the agnostic "relativity" of knowledge that philosophers have grown aweary of listening. But even this lethargy might be quickened by a moderate hospitality to the pragmatic interpre- tation. That red, or far and near, or hard and soft, or big and little, involve a relation between organism and environment, is no more an argu- ment for idealism than is the fact that water in- volves a relation between hydrogen and oxygen.* It is, however, an argument for the ultimately practical value of these distinctions — that they are differences made in what things would have been without organic behavior — differences made not by "consciousness" or "mind," but by the organ- ism as the active centre of a system of activities. Moreover, the whole agnostic sting of the doctrine * I owe this illustration to my colleague, Dr. Montague. JOHN DEWEY 67 of "relativity" lies in the assumption that the ideal or aim of knowledge is to repeat or copy a prior existence — in which case, of course, the making of contemporaneous differences by the organism in the very fact of awareness would get in the way and forever hinder the knowledge func- tion from the fulfilment of its proper end. Knowledge, awareness, in this case suffers from an impediment which no surgery can better. But if the aim of knowing be precisely to make cer- tain differences in an environment, to carry on to favorable issue, by the readjustment of the organ- ism, certain changes going on indifferently in the environment, then the fact that the changes of the organism enter pervasively into the subject-matter of awareness is no restriction or perversion of knowledge, but part of the fulfilment of its end. The only question would then be whether the proper reactions take place. The whole agnostic, positivistic controversy is flanked by a single move. The issue is no longer an ideally necessary but actually impossible copying, versus an improper but unavoidable modification of realit}^ through organic inhibitions and stimulations : but it is the right, the economical, the effective, and, if one may venture, the useful and satisfactory reaction versus the wasteful, the enslaving, the misleading, and the confusing reaction. The presence of organic responses, influencing and modifying every content, every subject-matter of awareness, is the 68 REALITY AS PRACTICAL undoubted fact. But the significant thing is the way organic behavior enters in — the way it influences and modifies. We assign very different values to different types of " knowledge," — or subject-matters involving organic attitudes and operations. Some are only guesses, opinions, sus- picious characters; others are "knowledge" in the honorific and eulogistic sense — science ; some turn out mistakes, blunders, errors. Whence and how this discrimination of character in what is taken at its own time to be good knowledge } Why and how is the matter of some "knowledge" genuine-know- ing and of other mis-knowing f Awareness is itself a blanket term, covering, in the same bed, delusion, doubt, confusion, ambiguity, and definition, or- ganization, logical conclusiveness assured by evi- dence and reason. Any naturalistic or realistic theory is committed to the idea that all of these terms bear impartially the same relation to things considered as sheer existences. What we must have in any case is the same existences — the same in kind — only differently arranged or linked up. But why then the tremendous difference in value ? And if the unnaturalist, the non-realist, says the difference is one of existential kind, made by the working here malign, there benign, of " con- sciousness," "psychical" operations and states, upon the existences which are the direct subject- matter of knowledge, there is still the problem of discriminating the conditions and nature of the JOHN DEWEY 69 respective beneficent and malicious interventions of the peculiar "existence" labelled consciouness/ The realness of error, ambiguity, doubt and guess poses a problem. It is a problem which has per- plexed philosophy so long and has led to so many speculative adventures, that it would seem worth while, were it only for the sake of variety, to listen to the pragmatic solution. It is the business of that organic adaptation involved in all knowing to make a certain difference in reality, but not to make any old difference, any casual difference. The right, the true and good, difference is that which carries out satisfactorily the specific pur- pose for the sake of which knowing occurs. All manufactures are the product of an activity, but it does not follow that all manufactures are equally good. And so all "knowledges" are differences made in things by knowing, but some differences are not calculated or wanted in the knowing, and hence are disturbers and interlopers when they come — while others fulfil the intent of the know- ing, being in such harmony with the consistent behavior of the organism as to reinforce and en- large its functioning. A mistake is literally a mishandling; a doubt is a temporary suspense and vacillation of reactions ; an ambiguity is the tension of alternative but incompatible mode of ' Of course on the theory I am interested in expounding, the so-called action of "consciousness" means simply the organic releases in the way of behavior which are the conditions of awareness, and which also modify its content. 70 REALITY AS PRACTICAL responsive treatment; an inquiry is a tentative and retrievable (because intra-organic) mode of activity entered upon prior to launching upon a knowledge which is public, ineluctable — without anchors to windward — because it has taken phys- ical effect through overt action. It is practically all one to say that the norm of honorable knowing is to make no difference in its object, and that its aim is to attain and buttress a specific kind of difference in reality. Knowing fails in its business if it makes a change in its own object — that is a mistake ; but its own object is none the less a prior existence changed in a certain way. Nor is this a play upon the two senses — end and subject-matter — of "object." The organism has its appropriate functions. To maintain, to expand adequate functioning is its business. This functioning does not occur in vacuo. It involves co-operative and readjusted changes in the cosmic medium. Hence the appro- priate subject-matter of awareness is not reality at large, a metaphysical heaven to be mimeographed at many removes upon a badly constructed mental carbon paper which yields at best only fragmentary, blurred, and erroneous copies. Its proper and legitimate object is that relationship of organism and environment in which functioning is most amply and effectively attained; or by which, in case of obstruction and consequent needed ex- perimentation, its later eventual free course is JOHN DEWEY 71 most facilitated. As for the other reaUty, meta- physical reahty at large, it may, so far as aware- ness is concerned, go to its own place. For ordinary purposes, that is for practical purposes, the truth and the realness of things are synonymous. We are all children who say "really and truly." A reality which is so taken in organic response as to lead to subsequent re- actions that are off the track and aside from the mark, while it is, existentially speaking, per- fectly real, is not good reality. It lacks the hall- mark of value. Since it is a certain kind of object which we want, that which will be as favorable as possible to a consistent and liberal or growing functioning, it is this kind, the true kind, which for us monopolizes the title of reality. Pragmatically, teleologically, this iden- tification of truth and "reality " is sound and rea- sonable : rationalistically, it leads to the notion of the duplicate versions of reality, one absolute and static because exhausted; the other phenom- enal and kept continually on the jump because otherwise its own inherent nothingness would lead to its total annihilation. Since it is only genuine or sincere things, things which are good for what they pretend to in the way of con- sequences, that we want or are after, morally they alone are "real." n REALITY AS PRACTICAL IV So far we have been dealing with awareness as a fact — a fact there Hke any fact — and have been concerned to show that the subject-matter of awareness is, in any case, things in process of change; and in such change that the knowing function takes a hand in trying to guide it or steer it, so that some (and not other) differences accrue. But what about the awareness itself ? What happens when it is made the subject- matter of awareness ? What sort of a thing is it? It is, I submit, mere sophistication (futile at that), to argue either that we cannot become aware of awareness without involving ourselves in an endless regress, or that whenever we are aware of anything we are thereby necessarily aware of awareness once for all, so that it has no character save this purely formal and empty one. Taken concretely, awareness is an event with certain specifiable conditions. We may indeed be aware of it formally, as a bare fact, just as we may be cognizant of an explosion without know- ing anything of its nature. But we may also be aware of it in a curious and analytic spirit, under- taking to study it in detail. This inquiry, like any other inquiry, proceeds by determining con- ditions and consequences. Here awareness is a characteristic fact, presenting to inquiry its own JOHN DEWEY 73 characteristic ear-marks ; and a valid knowledge of awareness is the same sort of thing as valid knowledge of the spectrum or of a trotting horse; it proceeds generically in the same way and must satisfy the same generic tests. What, then, is awareness found to be ? The following answer, dogmatically summary in form, involves positive difficulties, and glides over many points w^here our ignorance is still too great. But it represents a general trend of scientific in- quiry, carried on, I hardly need say, on its ow^n merits without respect to the pragmatic contro- versy. Awareness means attention, and attention means a crisis of some sort in an existent situa- tion; a forking of the roads of some material, a tendency to go this way and that. It represents something the matter, something out of gear, or in some way menaced, insecure, problematical and strained. This state of tension, of ambiguous indications, projects and tendencies, is not merely in the "mind," it is nothing merely emotional. It is in the facts of the situation as transitive facts ; the emotional or "subjective" disturbance is just a part of the larger disturbance. And if, employing the language of psychology, we say that attention is a phenomenon of conflicting habits, being the process of resolving this con- flict by finding an act which functions all the factors concerned, this language does not make the facts "merely psychological" — whatever that 74 REALITY AS PRACTICAL means.* The habits are as biologic as they are "personal," and as cosmic as they are biologic. They are the total order of things expressed in one way; just as a physical or chemical phenomenon is the same order expressed in another way. The statement in terms of conflict and readjustment of habits is at most one way of locating the dis- turbance in things; it furnishes no substitute for, or rival of, reality, and no "psychical" duplication. If this be true, then awareness, even in its most perplexed and confused state, a state of maximum doubt and precarious ness of subject-matter, means things entering, via the particular thing known as organism, into a peculiar condition of differ- ential — or additive — change. How can we re- fuse to raise and consider the question of how things in this condition are related to the prior state which emerges into it, and to the subsequent state of things into which it issues .^^^ Suppose the case to be awareness of a chair. Suppose that this awareness comes only when there is some problematic affair with which the * What does it mean ? Does the objectivity of fact disappear when the biologist gives it a biological statement ? Why not object to his conclusions on the ground that they are "merely" biological? ^ It is this question oj tfie relation to one other of different successive states of things which the pragmatic method substitutes for the epistemologlcal inquiry of how one sort of existence, purely mental, temporal but not spatial, immaterial, made up of sublimated gaseous consciousness, can get beyond itself and have valid reference to a totally different kind of existence — ■ spatial and extended ; and how it can receive impressions from the latter, etc., — all the questions which constitute that species of confirmed intellectual lock-jaw called epistemology. JOHN DEWEY 75 chair Is in some way — in whatever degree of remoteness — concerned. It may be a wonder whether that is a chair at all; or whether it is strong enough to stand on; or where I shall put it; or whether it is worth what I paid for it; or, as not infrequently happens, the situation in- volved in uncertainty may be some philosophic matter in which the perception of the chair is cited as evidence or illustration. (Humorously enough, the awareness of it may even be cited in the course of a philosophic argument intended to show that awareness has nothing to do with situations of incompleteness and ambiguity.) Now what of the change the chair undergoes in entering this way into a situation of perplexed inquiry ? Is this any part of the genuineness of that chair with which we are concerned ? If not, where is the change found ? In something totally different called "consciousness".^ In that case how can the operations of inquir}', of observation and memory and reflection, ever have any assur- ance of getting referred back to the right object ? Positively the presumption is that the chair-of- which-we-are-speaking, is the chair oj-which-we are-speaking; it is the same thing that is out there which is involved also in the doubtful situa- tion. Moreover, the reference to "consciousness" as the exclusive locus of the doubt only repeats the problem, for "consciousness," by the theory under consideration, means, after all, only tlie 76 REALITY AS PRACTICAL chair as concerned in the problematical situation. The physical chair remains unchanged, you say. Surely, if as is altogether likely, what is meant by physical is precisely that part of the chair as object of total awareness which remains unaf- fected, for certain possible purposes, by entering for certain other actual purposes into the situa- tion of awareness. But how can we segregate, antecedently to experimental inquiry, the " physical " chair from the chair which is now the object to be known ; into what contradictions do we fall when we attempt to define the object of one awareness not in its own terms, but in terms of a selected type of object which is the appropriate subject- matter of some other cognizance ! But awareness means inquiry as well as doubt — these are the negative and positive, the retro- spective and the prospective relationships of the thing. This means a genuinely additive quale — one of readjustment in prior things.^ I know the dialectic argument that nothing can assume a new relation, because in order to do so it must already be completely related — when it comes from an absolutist I can understand why he holds it, even if I cannot understand the idea itself. But apart from this conceptual reasoning we must follow the lead of our subject-matter; and when we find a thing assuming new relations * We have arrived here, upon a more analytic platform, at the point made earlier concerning the fact that knowing issues in action which changes things. JOHN DEWEY 77 in the process of inquiry, must accept the fact and frame our theory of things and of knowing to include it, not assert that it is impossible because we already have a theory of knowledge which precludes it. In inquiry, the existence which has become doubtful always undergoes experimental reconstruction. This may be largely imaginative or "speculative." We may view certain things as if placed under varying conditions, and consider what then happens to them. But such differences are really transformative so far as they go, — and besides, such inquiries never reach conclusions finally justifiable. In important and persistent inquiry, we insist upon something in the way of actual physical making — be it only a diagram. In other words, science, or knowing in its honorific sense, is experimental, involving physical construc- tion. We insist upon something being done about it, that we may see how the idea when carried into effect comports with the other things through which our activities are hedged in and released. To avoid this conclusion by saying that knowing makes no difference in the "truth," but merely is the preliminary exercise w^hich discovers it, is that old friend whose acquaintance w^e have repeatedly made in this discussion: the fallacy of confusing an existence anteceding knowing with the object which terminates and fulfils it. For knowing to make a difference in its own final term is gross self-stultification; it is none the less so when 78 REALITY AS PRACTICAL the aim of knowing is precisely to guide things straight up to this term. When " truth " means the accompHshed introduction of certain new differ- ences into conditions, why be fooHsh enough to make other and more differences, which are not wanted since they are irrelevant and misleading ? Were it not for the teachings of sad experience, it would not be necessary to add that the change in environment made by knowing is not a total or mi- raculous change. Transformation, readjustment, reconstruction all imply prior existences : existences which have characters and behaviors of their own which must be accepted, consulted, humored, manipulated or made light of, in all kinds of differing ways in the different contexts of different problems. Making a difference in reality does not mean making any more difference than we find by experimentation can be made under the given conditions — even though we may still hope for different fortune another time under other cir- cumstances. Still less does it mean making a thing into an unreality, though the pragmatist is some- times criticised as if any change in reality must be a change into non-reality. There are diflficulties in- deed, both dialectic, and real or practical, in the fact of change — in the fact that only a permanent can change and that change is alteration of a perma- nent. But till we enjoin botanists and chemists from referring to changes and transformations in their subject-matter on the ground that for any- JOHN DEWEY 79 thing to change means for it to part with its reaUty, we may as well permit the logician to make similar references. V Sub specie aeternitatis ? or sub specie genera- tionis ? I am susceptible to the aesthetic charm of the former ideal — who is not ? There are moments of relaxation : there are moments w^hen the demand for peace, to be let alone and relieved from the continual claim of the world in which we live that we be up and doing something about it, seems irresistible; when the responsibilities imposed by living in a moving universe seem intolerable. We contemplate with equal mind the thought of the eternal sleep. But, after all, this is a matter in which reality and not the philosopher is the court of final jurisdiction. Outside of philosophy, the question seems fairly settled ; in science, in poetry, in social organization, in religion — wherever reli- gion is not hopelessly at the mercy of a Frank- enstein philosophy which it originally called into being as its own slave. Under such circumstances there is danger that the philosophy wiiich tries to escape the form of generation by taking refuge under the form of eternity will only come under the form of a by-gone generation. To try to escape from the snares and pitfalls of time by recourse to traditional problems and interests 80 REALITY AS PRACTICAL — rather than that let the dead bury their own dead. Better it is for philosophy to err in active participation in the living struggles and issues of its own age and times than to maintain an immune monastic impeccability, without relevancy and bearing in the generating ideas of its contemporary present. In the one case, it will be respected, as we respect all virtue that attests its sincerity by sharing in the perplexities and failures, as well as in the joys and triumphs, of endeavor. In the other case, it bids fair to share the fate of what- ever preserves its gentility, but not its activity, in descent from better days; namely, to be snugly ensconced in the consciousness of its own respectability.

Bush In 1684 was published at Amsterdam a little book, probably seldom read, entitled "Recueil de quelques pieces curieuses concernant la philoso- phic de Monsieur Descartes," attributed to Pierre Bayle, The collection comprises six short pieces together with an introduction by the compiler ; and although these viewed as systematic philosophy are of no particular interest, yet as a specimen of the discussions which gathered about the Carte- sian movement toward the end of the seventeenth century, more than thirty years after the death of Descartes, and as an index of the intellectual situa- tion in which the Cartesian philosophy was obliged to work out its development, the Recueil may be deserving of some attention. The editor laments the difficulty of publishing books of liberal tendencies in France, where the Inquisition "is making rapid progress." Publi- cation without the official permit, extremely diffi- cult to obtain for liberal books, meant that the work thus issued could hardly be circulated. The contents of the Recueil being on this account 83 84 A FACTOR IN IDEALISM extremely rare, the compiler caused them to be published in Holland, where, inasmuch as the Refor- mation had been politically successful, works on philosophy were not liable to be suppressed in the interest of Thomas Aquinas and the French monarchy. The first piece in the collection is the text of an agreement between the Jesuits and the fathers of the Oratory, according to which the latter under- took to cease teaching certain opinions which the former did not approve, and in particular to cease teaching the Cartesian philosophy. The para- graphs which bear directly upon the philosophy of Descartes are as follows : " Dans la physique Ton ne doit point s' eloigner de la physique ni des principes de physique d'Aristote commun^ment re9us dans les colleges pour s'attacher a la doctrine nouvelle de Monsieur Descartes, que le Roi a defendu qu'on enseignat pour de bonnes raisons. L'on doit enseigner: 1. Que I'extension actuelle et ext^ri- eure n'est pas de I'essence de la matiere. 2. Qu'en chaque corps naturel il y a une forme substan- tielle reellement distinguee de la matiere. 3. Qu'il y a des accidens reels et absolus inh^rens k leurs sujets, reellement distingues de toute autre substance, et qui peuvent surnaturellement etre sans aucun sujet. 4. Que Tame est reellement presente et unie a tout le corps et a toutes les parties du corps. 5. Que la pensee et la connaissance n'est pas de I'essence de Fame WENDELL T. BUSH 85 raisonnable. 6. Qii'il n'y a aucime repugnance que Dieu puisse produire plusieurs mondes a merae temps. 7. Que le vide n'est pas impossible." These propositions are preceded by certain re- quirements in regard to instruction in theology, the purpose of which can only have been to weaken certain doctrines of Augustine, to whom the Ora- tory was much attached. It is significant that Augustine and Descartes are here included under a common prohibition. The second piece is in the nature of a reply to the above agreement; it criticises particularly the hostility of the Jesuits toward Saint Augustine and their endeavor in the above-mentioned contract to undermine his authority. The editor's explanation of the third piece I will transcribe. "To better understand the history of the other pieces, you must know that in the year 1680 a Jesuit of Caen, the Pere de Valois, assuming the name Louis de la Ville, published a treatise entitled Sentimens de Monsieur Descartes touchani V essence et les proprietes du corps opposes a la doc- trine de Veglise et conformes aux erreurs de Calvin sur le sujet de VEucharistie. He dedicated it to the French clerg)' and exhorted the prelates to re- pair at once the great evil Avith which the church was threatened by the Cartesians. He begged them in the name of France to pronounce sentence of condemnation against Cartesianism, and in order to influence them with a reason which he knew to 86 A FACTOR IN IDEALISM be all powerful in its effects upon their minds, he referred to a decree of the council of state and to a lettre de cachet which had forbidden the teaching of a Cartesian professor. The book alarmed the entire following of this philosophy; M. Regis, the celebrated Cartesian, was obliged to break off his lectures in Paris, and in addition, was unable to obtain a license to publish a work on philosophy which he had long since completed. Each feared lest he be obliged to sign a declaration or be excom- municated as a heretic. Thereupon M. Bernier . . . caused to be printed secretly a little book, the third piece in the collection, of which he distributed a few copies to his friends and even to a few prelates. He agrees that critics may say whatever they please of the Cartesians, and he declares strongly against some of their opinions in order the better to make his peace ; and for the rest, having as much reason as they to fear the charge of heresy in the matter of transubstantiation, he does what he can to establish his innocence." In general M. Ber- nier's defence of the Cartesians takes the line, not of denying their obligation to make their meta- physics conform to the Council of Trent, but of arguing that their Jesuit critic has not correctly stated the orthodox position. This critic had written with a particular animus against Malebranche, and a portion of the essay discusses the nature of original sin in infants. M. Bernier seeks to justify Malebranche on this point against M. de la Ville. WENDELL T. BUSH 87 With sucli problems was the philosophy of that day forced to occupy itself. The fourth essay in the Recueil is a Memoir e pour expliqucr la possibUite de la transubstantiation, attributed to Malebranche. This essay, the editor observes, was regarded with all the more suspicion "since it explained the Roman Eucharist accord- ing to the hypotheses of the new philosophy in a way wholly different from that to be found in the writ- ings of M. Descartes or of M. Rohault or of M. Maignan." This new explanation was evidently intended to meet the difficulty which the imagina- tion encountered in assenting to the orthodox pos- tulate that wherever there was a consecrated host there existed the complete and entire body of Christ. It is a unique case of the one and the many, but since, says Malebranche, in any prod- uct of art the unity of the created thing is derived from the will of its creator, so the apparent diver- sity of many bits of bread and many portions of wine is no hindrance to their essential unity. The fifth piece is by a professor at Sedan, pre- sumably Bayle himself, and is a refutation of M. de la Ville's efforts to disprove by the *' light of reason" the Cartesian theory of the essence of body. And now we come to the editor's statement of his purpose in publishing this collection. "It is clear that the Council of Trent has decided not only that the body of Christ is present wherever there are consecrated hosts, but also that all the 88 A FACTOR IN IDEALISM portions of his body interpenetrate each other. It is clear from the book of M. de la Ville that this decision is wholly incompatible with the doctrine that the entire essence of matter is comprised in its extension. It is clear from the comments of M. Bernier and of Malebranche that their man- ner of explaining transubstantiation is not that w^hich is clearly contained in the words of the Council. Finally it is clear from the dissertation of the professor of Sedan that it is as impossible for matter to be penetrated as it is for two things to be equal when one is greater than another. It is therefore clear that the Council of Trent decided falsely when it spoke of the presence of Our Lord upon the altars." If only the Roman Catholics would avail themselves of clear and distinct ideas in this matter, says Bayle, they would recognize their errors and might then welcome the co- operation of the Cartesians in formulating a doc- trine of the Eucharist to which the followers of Calvin could assent. One essay remains. It is a series of ten medita- tions modelled on the Meditations of Descartes. A rather characteristic sentence may be quoted. "My will . . . is an impression or a movement that God has put into me by which he impels me toward himself as all good and all being.'* These little pieces were put together by a very gifted man with a perfectly serious purpose. He did not regard them, apparently, as unusual or WENDELL T. BUSH 89 eccentric. On the contrary, one's impression is that he regarded them as entirely normal and reason- able concerning a point of the utmost consequence. Certainly if Bayle had not regarded the transub- stantiation controversy as concerned with a genuine and vital problem he would have shown a capacity for intellectual detachment altogether exceptional. And if he had regarded the problem as having a social and political significance, rather than a truly metaphysical one, he could not have discussed it without reference to its metaphysical presuppo- sitions. And now for the reflections which such a book may stimulate. When Descartes took a hand in helping along the transition from the Middle Age there was much concern lest he leave no place for saving an article of faith to which the Middle Age had been particu- larly attached, — the doctrine of transubstantiation. This was a really burning issue; no philosopher who desired a hearing in the French world of letters could afford to be identified with the party of Calvin, and uncertainty on the question of the Eucharist pointed toward uncomfortable heresy. Even Descartes, although not believing in the in- dependent accidents, was persuaded to make two attempts at reconciling his conception of substance with the necessities of dogma, and several of the minor Cartesians made enthusiastic endeavors to explain the miracle of the Mass by the principles of the new philosophy. The significance of these 90 A FACTOR IN IDEALISM undertakings, seemingly so unimportant for phi- losophy, is by no means slight for the history of it. In the process of putting off medisevalism, western Europe endured the throes which we call by the name of the Protestant Reformation. The wars of religion in France had, to be sure, come to an end, but the sentiments which those wars had kept alive were still active, and if the fighting had not been really for points of dogma, it was neverthe- less under the banner of religious demands ; and the party antipathies and social rivalries incidental to the whole situation necessarily kept men's interest tense and keen in whatever points of theology might seem to be involved. The dogma at the focus of things was the Eucharist, and the Council of Trent had reaffirmed the orthodox position on this matter with all the emphasis at its command. While many speculative minds might be a Httle weary of St. Thomas, they were the more anxious for a plausible propping of their faith; for the Reformation had brought with it a real quickening of religious interest, and the dogma about which so much passion had gathered got the benefit of this revival. How should a thing so important, seemingly so fundamental, as transubstantiation have its existence solely in men's pious and inquis- itorial minds ? For it must be remembered that people were really excited about transubstantia- tion, and the natural question to ask concerning a new kind of philosophy was where it stood on WENDELL T. BUSH 91 this question. A man of such rare independence and self-control as Descartes, with a bent of genius which impelled him to the exact study of nature, and with none of the obligations incidental to a university position, could be indifferent to the metaphysics of the Eucharist; but even so, such indifference would probably result rather from concentration upon his proper business than from an insight into the mythical nature of the problem ; and Descartes wished and tried to remove incon- gruities between his philosophy and the popular faith. With the most sincere good will, however, the thing was impossible. The claim that exten- sion constituted the essence of bodies would not square with the necessities of the Tridentine dogma. This did not seriously disturb Descartes. He could seclude himseK in Holland and carry on patient researches, withholding his conclusions, if that seemed best, for publication after his death. But the subsequent development of his doctrines he must leave to others. How will it be when the fol- lowers of the master lack his scientific genius, and are, for the most part, university professors or churchmen under the French monarchy at the epoch of its culmination ? This reference to transubstantiation may serve to remind us of the atmosphere in which "modern" philosophy, to speak conventionally, had its begin- nings on the continent, and to orient us a little in a period that intellectually must have been tlie 92 A FACTOR IN IDEALISM most exciting one since the time of Augustine. The equanimity with which we to-day contem- plate the group of rival metaphysical theories was then undreamed of. The tradition was of a single body of doctrine which had all the importance of truth itself. The blend of Aristotle and Aquinas, secure in the universities, was not to be ousted from its strongholds by a new philosophical way of put- ting things, unless the new way took account of the problems that seemed important, and satisfied certain dominant interests better than the Peripa- tetic tradition could do. It was quite inevitable therefore that, under the conditions provided, meta- physics should continue to be concerned chiefly with what we may call theological problems. Had the Cartesians been anxious to avoid theological issues, a persecution conducted by theological con- servatives made such detachment impossible. Even in Holland, the new philosophy was denounced as contrary to the Bible and inimical to the civil power. Descartes himself was called a Jesuit and an atheist. In France Cartesianism was identified with Calvinism and, what was more dangerous, with Jansenism. Reference has already been made to the agreement according to which the Oratory, to avoid serious calamity, bound itself to abjure Descartes, and to mutilate its interpre- tation of Augustine. I should perhaps apologize for dwelling upon facts and conditions generally known and acces- WENDELL T. BUSH 93 sible to all in books which describe the period. My excuse is that the bearing of these facts and conditions upon the evolution of metaphysical concepts has not been generally appreciated. His- torians have not been suflficiently concerned with philosophy, nor philosophers with history', to esti- mate the influence of the sentiments of the later Reformation upon subsequent philosophy, and to relate certain modern results to these sources. But to resume: the Cartesians did not wish to avoid theological problems, for these seemed the most important of all problems, and to provide the special business of philosophy. The innova- tors in metaphysics were engaged in combating the system of philosophy endorsed by the Council of Trent, and Cartesianism had, accordingly, a certain kinship with the Reformation doctrines, in so far as both Cartesians and Calvinists were agents in the same process of historical tran- sition. The harrying of the Cartesians had its natural result. In Holland they tried to prove that Descartes was in the Bible and in France tliat he was in Aristotle. Louis XIV sought to make atonement by persecuting nonconformity. It was no light matter for a man of prominence to defend opinions obnoxious to the Jesuit order. Bouillier (Histoire de la philosophie Cartesienne) states that the most active persecution of the Cartesians was during the period 1675-1G90. Although this per- 94 A FACTOR IN IDEALISM secution did not diminish the vogue of Cartesian- ism, it did serve to keep metaphysics tied up to theology. The whole situation could not fail to develop habits of mind such that the problems of philosophy expressed a theological tradition rather than a free curiosity about nature and an interest in man's natural welfare. Very significant is the method by which the opinions of Descartes were first publicly taught. For a considerable time they had to be introduced under the cloak of St. Augustine. One of the argu- ments in support of the theory of animal automat- ism is characteristic. Since animals have not sinned, God would be unjust if they were to suffer pain. And the facility with which Cartesianism could be taught under the authority of Augustine points to a feature of Descartes 's thought that is in this connection of particular consequence. Descartes in all his writings forces the idea of God to the front, and seeks to give the impression that the validity of all subsequent conclusions depends upon the certainty of God's existence. All scien- tific knowledge of nature and man is made to appear as contingent upon a knowledge of God. This as- pect of the new doctrine appears to have given the liveliest satisfaction, and it is easily understood as soon as we see how it reproduces the most funda- mental conviction of the Reformation. This was the Augustinian exaltation of God and belittling of man. It was Augustine who supplied the patristic WENDELL T. BUSH 95 authority for the Reformation by his doctrine of predestination, from which it followed that the sacraments must be wholly ineffective as efi'orbs to interfere in the distribution of grace. Man with the burden of Adam's sin upon him was quite in- capable of bringing his will into agreement with God's will, without the gift of undeserved grace. The opera operata could avail nothing. All de- pended upon God in the matter of salvation, as it did in the Cartesian epistemology, and therefore it was that Descartes, although he was no Calvinist, yet, being opposed to mediaivalism, could not fail to be impressed with this, for his day, modern sen- timent. For although the Reformation in France had failed politically, yet the Augustinianism of the movement had been taken up by those of the clergy who, while aiming at the mo.>t i)erfect ortho- dox), yet wished to purify the church of all that had given just ground for criticism. This really spiritual wave of the Catholic reaction bore Des- cartes into the haven of popular approval in France. His demonstrations of the existence of God and the immortality of the soul gave such satisfaction that Cartesianism came to be regarded as the precious ally of conservative religious faith. But if the backing of the Oratory wiis worth so much to Cartesianism, it could not fail to influence its subsequent tendencies by keeping the attention of "philosophers" concentrated upon the meta- physical presuppositions involved in tlie idea of 96 A FACTOR IN IDEALISM the soul, separable from the body, the vehicle of sin and the object of grace. There is nothing remarkable, then, in recognizing that the opinions, on what seemed fundamental problems, of the men who were engaged in win- ning an intellectual emancipation from Thomas Aquinas, constituted the natural metaphysics of what we call the Protestant Reformation. The affinity with Augustine was immediately recog- nized and made use of; in the Occasionalists we find very frankly stated that entire dependence of man upon God which the reformers were so fond of emphasizing, while both the Cartesians and the Huguenot party were fighting the same enemy, the authority of the scholastic tradition. The effect of it all is that modern philosophy has been, in the main, not free inquiry but Protestant meta- physics, and its central problem, the problem of knowledge, has been determined, not by an exam- ination of cognitive experience but by an elabora- tion of traditional preconceptions in harmony with the dominant interests of the later Reformation. The problem of knowledge naturally arose as soon as the Cartesian ideas of substance made knowl- edge a mystery. The definition of the soul, how- ever, after the manner of " conscious substance," denying to it all power of affecting or being affected by the world about it, actually proved to be particu- larly gratifying to a very large public, as it seemed to be a sufficient demonstration of the soul's im- WENDELL T. BUSH 97 mortality; and it was to be expected that these presuppositions which made knowledge something wholly unintelligible should be nursed and forti- fied. The immense vogue enjoyed by Malebranche, the pride in his development of Cartesianism, the authority conceded to his pious metaphysics, re- veal clearly enough the inevitable current. Another circumstance which kept philosophy in the land of impassioned mythology was the burden of responsibility for Spinoza. "Is Descartes the father and the accomplice of Spinoza, or is his philosophy the antidote of Spinozism ? Is Des- cartes the builder or the destroyer of the new doc- trine, Spinozismi architectus aut eversor? according to the titles of polemical tvtI tings on opposite sides. This was the question debated from the start with singular vivacity^ between the Cartesians of Holland and their opponents. Moreover, the two parties competed with one another in casting abuse and anathemas at the wretched autlior, and the Cartesians exclaimed the louder, in order to avert from themselves the suspicion of having anything in common with this man." ^ And in Leibniz we find a man of altogether exceptional gifts dishing up the old wine of mediaeval faith, and seeking to reconcile the two confessions on the problem of the Eucharist. Meanwhile, British philosophy, starting with the same conception of knowledge, as the states of ' Bouillier: "Histoire de la philosophic Cart^sienne," Vol. I, p. 416. 7 98 A FACTOR IN IDEALISM an ambiguous substance, developed in an environ- ment characterized by the attempt to base theo- logical guarantees upon innate ideas, by the deistic controversy, and by a certain influence of Carte- sian thought. That little discourse between five or six friends which brought the participants to a stand and was the occasion of Locke's "Essay" was concerned, we are told, with the principles of morality and revealed religion. However empirical Locke's own temperament may have been, he was quite unable to disregard the problems that agi- tated the world about him. Calvinistic theology was in the ascendant, and Locke grew up among the English dissenters. It was not likely that any one made of milder stuff than Hobbes would be sufficiently sceptical about the soul to doubt its capacity to become the locus of mental processes. Whether we use the term soul, mind, or conscious substance makes no particular difference. " The soul " is the parent concept of all such notions. The history of British philosophy shows an increasing emphasis upon "states" of mind, and an increas- ing scepticism toward the "substance" supporting them. Taking the concept of conscious substance naively, as did the Cartesians, states of conscious- ness are evidently the accidents of this type of sub- stance, and when the substance has been criticised away, as by Hume, or given a radically different meaning, as by Leibniz, consciousness, like the independent accidents of the Mass, becomes a com- WENDELL T. BUSH 99 plete and finished metaphysical instrument. The separation accompHshed, physiological arguments serve to justify it; they may even have made tlie separation easier; but without the conception of a soul and its states, a mind with its ideas and impres- sions, it is hard to see how such a notion as con- sciousness could ever have been born. The soul : w^hence came such a singular idea as that of this immaterial, immortal, cognitive entity ? It was natural for Christian metaphysics to lay great stress on the individual subject of salvation. It was natural for the soul, w^hose precarious state was the justification of the church, to take a prom- inent place in the dogmatics of Augustine, But there is nothing like a controversy to call forth the full measure of ingenuity and eloquence in de- fence of such an idea, and the current emanation theories, particularly as defended by tlie Mani- chseans, had implications which so vahant a churchman could not tolerate. If we assume the agency of a literary tradition, the presumption is that the soul doctrine came to Augustine from Plato. There is ratlier much in Plato about the soul. It seemed to him extremely important to prove its immortality, but Plato knows no problem as to the existence of the soul. That is never questioned. This perplexing thing, the seat of personahty, imprisoned for the time being in the body and contaminated by it, the source of motion, the principle of life, — one 100 A FACTOR IN IDEALISM would like to know where Plato got such a curious idea. Nearly all primitive races might, no doubt, have provided him with something of the sort. Actually, however, the idea appears to have been the chief concern of the contemporary mystery organizations, in which the conception of the soul was made to do very much the same kind of serv- ice it did for Plato ; and its injection into philoso- phy may well have a good deal to do with its usefulness for the purposes of the Orphic cults. The question of the origin of the soul-idea is a problem in the study of primitive culture. The experience of dreams, the mysteries of birth and death, customs of totemism, the imitative magic of harvest rites, in such phenomena must the notion of soul have originated. Or, if we regard the Or- phic mysteries as the beginning of that tradition which has dominated the history of philosophy even down to the present day, then the concept of consciousness, or its parent concept, the soul, may yet be traced, perhaps confidently, to the blood of the bull Dionysos. But whether the line of tradition from primitive beliefs to the metaphysics of the seventeenth cen- tury was the one here suggested, or whether the connection was through other channels, makes no difference to the main thesis of this paper. His- torically, the concept of consciousness was evolved by cutting conscious substance away from its own accidents. The notion of such a substance derives WENDELL T. BUSH lOl ultimately from primitive culture. These consid- erations may be philosophically irrelevant, but they ought to interest that small though growing num- ber of students who beheve that history should be history even though it be the history of philosophy. If the Renaissance could have run its course un- confused by the odium theologicum, tlie rediscovery of nature and man might have brought philosophy down from heaven to earth, to find there her natural occupation. But this was not to be. There was the Reformation and the Council of Trent and the Thirty Years' War; Calvin, Port Royal, Male- branche, and Leibniz. Was it not inevitable that, not nature and man as humanly experienced, but the soul, the w'orld and the deity as metaphysically conceived, should be the theme of "modern" phi- losophy ? Why be surprised tliat the metaphysics based on the concept of consciousness seems to have more to do with some other world than with this one ? It is the pride of idealism that instead of guiding the work of actual knowledge, instead of throwing helpful light on the technique of discovery, this type of philosophy has, in the main, issued in religious metaphysics. Nevertheless, the initiators of modern philosophy were surely seeking some- thing very different, and from their point of view this failure to escape from theological reminiscence must appear as fundamental failure. It has been my purpose to ask why this is so, and to suggest the lines along which an intelligible 102 A FACTOR IN IDEALISM answer could be attempted. The recent meta- physics which has sought to guarantee a "spir- itual" conception of things has been erected on the foundation of an animistic survival from primi- tive culture. That philosophers themselves have shown for the most part little interest in such his- torical connections is readily understood. Not many years have elapsed since most of the com- petent thinkers in the field of metaphysics defended one form or another of idealism, and a certain com- placent assurance of being at least on the right track made most of them indisposed to regard their "truth" as an historical episode; while one effect of the theory of evolution has been the dis- position to assume that the most significant thing about the past is that it was a preparation for the present. And as for the present, it seems inevit- ably human to regard it, not as history, but as a specimen of eternity. When Professor James asked his epoch-making question "Does consciousness exist .'^" he let in the kind of light that is often more salutary than wel- come. Not less emancipating was his declared belief that consciousness is "the faint rumor left behind by the disappearing 'soul' upon the air of philosophy." CONSCIOUSNESS A FORM OF ENERGY CONSCIOUSNESS A FORM OF ENERGY By Wm. Pepperrell Montague 1 HE most perplexing and perhaps the most cen- tral of philosophical problems is the problem of the nature of consciousness and the manner of its relation to the world which it reveals, but in which it also abides. A physical influence of some sort, a fact accessible to the external perception of more than one observer, is propagated along a nerve fibre, and at a certain period in its progress there occurs a fact of an entirely different nature, to wit, a psychical fact which is accessible to the internal perception of only one observer. Nature in her transmutations of energy affords many instances of disparateness between the antecedent and conse- quent stages of a process, but in none of them is the consequent a member of a different order of being from that of the antecedent. Between the consciousness of an object or of a quahty and the neural process which antecedes and perhaps accom- panies that consciousness there is a difference far transcending all differences of quality, magnitude, time, and place with which physics is conversant. The system of physical objects seems to be a closed 105 106 CONSCIOUSNESS AS ENERGY system, complete in itself, in which no room can be found for the individual's consciousness of those objects. And yet the consciousness of objects is an undeniable consequence of certain processes in those objects. Now it is at once the aim and the duty of science to reveal everywhere the hidden continuity that must underlie the most seem- ingly discontinuous of changes. And the great- ness of the change from stimulus to sensation may in nowise excuse a neglect of the puzzle presented therein. The clear- thinking Cartesians were the first to realize the crucial nature of the psychophysical problem, and the first to make a sustained and serious attempt at its solution. They failed; and those who came after inherited from them not their fine passion for the problem itself but only that false antithesis of consciousness and extension which had made failure inevitable. Since then there have been several attempts to explain away the problem by means of a general idealistic meta- physic, or to restate it in such a way that the differ- ence between physical and psychical should appear as a purely functional or methodological distinc- tion. But for the most part both science and phi- losophy have resigned themselves to the acceptance of an inexplicable concomitance or "parallelism" between the physical and psychical series of events, a working hypothesis that is relatively independent of ultimate theories concerning the primacy of one WM. PEPPERRELL MONTAGUE 107 or the other of these series. Quite recently, how- ever, there has grown up both here and abroad a new interest in the nature of consciousness and a new kind of protest against the epistemology of ideahsm. These current attempts to revive real- ism by combining with it a direct or presentative theory of knowledge (the "new realism"), and cor- relatively to define consciousness as a relation be- tween objects rather than a substance in which they inhere, promise much of interest and value. But I believe that they will fall short of their own ideal, should they persist in separating the problem of the nature of consciousness from the problem of its genesis. A definition of conscious- ness either as a relation of implicativeness which under certain conditions subsists between objects (Woodbridge) , or as a diaphanous medium through which on occasion objects are united (G. E. Moore), seems to me to require supplementation. For such definitions, however apt in their estimates of the properties of a psychosis as revealed in introspection, are not designed to throw light upon the physical and physiological conditions of its origin. Nor can the psychophysical problem which so perplexed the Cartesians be brusquely dis- missed as a question pertaining exclusively to the mechanism of consciousness. If evolution has taught us anything in scientific method, it has taught us that a sound definition will throw light on the genesis of that which is defined. Now it is 108 CONSCIOUSNESS AS ENERGY by no accident that the mind has a body ; and the fact that sensations follow upon stimuli is not irrel- evant to the nature of sensations. The problem of the nature of consciousness is, in short, irremedi- ably involved in the problem of its mechanism, and the latter problem is dual, including as it does the question of how conscious elements are related to neural currents, and the broader question of the relation of consciousness as a whole to the living organism, without which as a matrix the mind could neither begin nor, so far as we yet know, continue to exist. In the following investigation of the nature of the psychical, I propose to examine conscious- ness (1) from the standpoint of introspection; (2) from the external standpoint of its relation to stimuli. Lack of space precludes consideration of the third and still larger problem which concerns the relation of consciousness to the general life- process of the individual. Consciousness from within: Psychosis and Hylosis When we examine introspectively (or retrospec- tively) a direct perceptual experience, it appears to contain (1) elements which, while they momen- tarily belong to our experience, seem in no sense to be its peculiar property. We regard these ele- WM. PEPPERRELL MONTAGUE 109 ments as mere sojourners and transients in our consciousness, entering or leaving it at pleasure, belonging at the same time to other experiences than ours and capable of existing in their own right apart from any of these experiences. Such objects are the chairs, stones, stars, animals, etc., that we call physical. We find (2) a quite different set of elements, such as feelings, desires, volitions, etc., which seem to stand in no such loose and dissoluble relations to our experience. We can conceive of them neither as parts of another experience nor as capable of subsisting in their own right apart from any experience or consciousness of them. These elements are called psychical. We find (3) a cer- tain relational form or structure applicable to the experience as a whole, and also to the psychical parts of it, but not applicable to the first named or physical elements. The physical elements are then distinguished from the psychical not only by their capacity to exist in many experiences or in none, but also by their possessing a form or struc- ture that is in some respects the antithesis of the psychical structure, which latter is also the structure of the experience as a whole ; and it is in their con- trast of structure rather than in their contrast of content that the most promising basis for a clear distinction between physical and psychical is to be found. The problem of further defining the psychical is indeed complicated at the outset by the consider- 110 CONSCIOUSNESS AS ENERGY ation that while the physical is capable of becom- ing a part of the psychical system, from which it is to be distinguished, yet from another point of view the physical world may be regarded as itself con- taining the totality of the very experiences which reveal and contain it. We might compare the situation to a lake in which there were a number of whirlpools, through each one of which all the water flowed or could flow. The water (physi- cal objects) could then be said to be contained in the whirlpools (consciousnesses), while at the same time the whirlpools themselves would be in their turn contained in the water of the lake. Let us seek to formulate the differences in structure of these two curiously interpenetrating systems. The physical world and every portion of that world is a system in which the plurality of the elements is primary and the unity of the system is secondary. Every material object is conceived as being susceptible of indefinite division and sub- division into parts. Whatever is physical is es- sentially plural; such unity as pertains to it is factitious or external. This essential divisibility or compositeness of material objects is the real justifi- cation for formulating their behavior in terms of atomistic and mechanistic analysis. We never rest satisfied with the view of one object influenc- ing another by means of its nature or quality, for we know that that nature or quaUty is dependent WM. PEPPERRELL MONTAGUE 111 upon the parts of the thing and upon their rela- tions. And the reduction of quahty to quantity in the physical world rests on the fact that qualities act only vicariously ; never in their own right but always as the correlates of spatio-temporal relations. The static aspect of this truth is evidenced in our appreciation of the impossibility of a quality or universal having physical existence apart from matter. It must inhere in the latter as its state or accident. In the material world a thing must be before it can be somewhat. Let us turn now to a consideration of the struc- ture of a psychosis, by which term is meant an individual's consciousness -of- objects or total experi- ence at any given moment. Like a material system (which for convenience we may name a "hylo- sis"), every psychosis possesses both unity and variety. But the plurality of elements in a psychi- cal system is always secondary and subordinate to its unity as a whole. My experience of ten inches is by no means composed of ten one- inch experi- ences. I cannot possibly imagine that experience divided up into separable parts. And as in the ma- terial system we found the compositeness of the whole reflected in the compositeness of each of its parts, so in the psychosis we find the unity and in- divisibility of the whole repeated in the similar unity and indivisibility of each psychical element. My consciousness of the room, for example, in- cludes my consciousness of the table. The con- 112 CONSCIOUSNESS AS ENERGY sciousness of the table includes the consciousness of the table's legs. But it would be as impossible to separate my consciousness of the table-legs from the consciousness of the other parts of the table, as to separate my consciousness of the table from my consciousness of the room. Unity or indivisibility is as fundamental a property of the experiencing manifold as plurality or divisibility is of the experi- enced manifold. We must not interpret this to mean that the physical world lacks quality and unity or that the psychical lacks quantity and plu- rality. Each order contains as much of both quan- tity and quality as does the other; only in the physical world it is the qualities that are secondary and factitious while in the psychical the reverse is true. But let us see to what extent this abstract formulation of the differentia of the psychical can serve to explain certain of its other and more familiar properties. The first of these subsidiary characteristics to which I would call attention is the psychical status of class -concepts, universals or attributes in their relation to the particular things in which they in- here. It often happens in my own experience, and I presume in that of others, that the quality of a sensation is perceived before the local sign or par- ticular place to which that quality will be referred. A sound or even a color is appreciated as such and only later is it viewed as an attribute inhering along with other attributes in a particular object. And WM. PEPPERRELL MONTAGUE 113 as, in direct experience, the only meaning we can give to a "thing" in distinction from its "states" is the definite position in the spatio-temporal system in which those states or qualities are exemplified, I interpret this felt priority of a quality to its local sign as justifying in the sphere of a psychosis the Platonic contention of the primacy of class-jorms or natures to the class-members which embody them. And if this primacy be questioned in the case of sense experience, I feel sure it will be accepted as holding true of the more conceptual phases of our mental life. We have to know the meaning of a general term before we can apply it to particular objects. The members of a class are, for thought, primarily only the more or less accidental embodi- ments of a certain nature or meaning. And this latter may be analyzed and discussed in complete disregard of whether or not it happens to be actu- aUzed here, there, or anywhere. Professor Wood- worth's discovery of the imageless or non-sensorial elements of many clearly defined topics of thought and plans of action gives striking emphasis to the truth in question ; though even without appeal to these non-sensory elements it seems to me, as I have said, easy to imagine a specific nature without also imagining it as existing at a particular place, i. e., as a particular object. I can certainly think of making a journey to San Francisco without con- sidering whether I shall go by way of Chicago or by way of St. Louis, this week or next week or 8 114 CONSCIOUSNESS AS ENERGY never. What the British nominahsts thought they had proved was the impossibiHty of conceiving uni- versal or abstractions. What they really did prove was the impossibility of conceiving universals or abstractions as particular physical objects. The same innocent and irrelevant truism had been tri- umphantly established, some centuries before, by Aristotle against Plato in the Tptros avOpoiiroq. In a psychical system the universal is primary and the particular secondary for the same reason that in a physical system the reverse is true — that reason being that the quantity and plurality of a physical system underlie its quality and unity, while in the psychical system it is the unity and quality that are fundamental. That the mind is the place of forms is one of the well-known criteria for distinguishing it from matter, and is directly deducible from the differentia that we have adopted. A second and even more familiar characteristic of the psychosis is its capacity for past and future events, for memory images, and for ideals. In the physical world the present is real; the past was and the future will be real, but only the present is. It is then a distinguishing feature of tlie psychical that in each present moment of its flow the past not only was but is present — as remembered, and the future not only will be but is present — as imagined. We might put it this way : at or in each moment of physical time only that one moment is present, while within the unity of WM. PEPPERRELL MONTAGUE 115 each moment of psychical time, many other mo- ments both past and future are present. This curious capacity of the psychical to extend in time, although it has been made the basis for the time- less egoes of subjective idealism, is in no wise in- compatible with the mind's presence in time. It is this extra dimension which more than any one thing gives to the conscious being his supreme advantage in competing with beings not conscious, enabling him, as it does, to respond to the impulse of the moment in the light of past knowledge and future needs. And yet this temporal unity of specious past and future in each actual present is but an- other aspect of the unity of my perception of one part of the spatial field with my perception of the other parts of that field. A third of these subsidiary marks of the psychi- cal, and one closely consequent upon tlie last, is the purposive or teleological character of mental causality as contrasted with the "blind" or me- chanical causality of the physical world. The goal of a conscious process is present from the be- ginning and takes an active part in selecting the links that lead up to its realization. This would be an impossible paradox in a purely material system, for the future as such has no physical ex- istence except at the moment when it ceases to be future ; and all causes act on the instant, ab extra or mechanically, the telos of the process playing no part in its own actualization. In a psychosis 116 CONSCIOUSNESS AS ENERGY the individual elements instead of being self- existent constituents of an aggregate are each of them subordinate both in their being and in their behavior to the structure or form of their system. If the tendency of the system as a whole be identi- cal with the tendency of one of its elements, then in the ensuing process that element will have a very peculiar prominence. Though not neces- sarily strong in its own right it will act catalytically as a kind of centre about which the other elements will gradually be distributed. A possibility-element in a psychosis differs from a fact- element in not being able to maintain itself except by aid of other elements. When we experience a future ideal in process of gradually attaining to what we call actu- alization, we note its passage from a parasitic or dependent position in our psychosis to a status of self-dependence and self- existence. And when the process is voluntary we perceive the other ele- ments contributing to this change of status in re- sponse to the demands of the system as a whole. Factuality, indeed, differs from possibility not merely as present and past differ from future, but as the fixed and must-be-admitted differ from the dismissible- at- pleasure. Facts are. They are also stubborn. Ideals are unborn things of the future; they dwell dimly in the conceptual fringe of our consciousness and clamor or plead accord- ing to their natures for us to incarnate them in its perceptual nucleus of fact. Teleological causation WM. PEPPERRELL MONTAGUE 117 is not then the mere influence of a conceived future element upon other elements of the psychosis. Self- active and self-directive, it is a movement of crys- tallization on the part of the psychosis as a whole towards and around one of its own members — a, movement in which the factual elements are, de- spite their individual tendencies, made to adapt themselves to the reception into their own order of the element which, though present with them, is nevertheless future and so of a different order. Thus, inadequately, I have attempted to depict the three traditional marks by which conscious- ness is contrasted with the real though passing show of its physical objects. These marks of mind were (1) its capacity for forms or universals; (2) its capacity for the non- actual things of the past and future, and (3) its capacity for self- directed and teleological causality : — psychical realism versus physical nominalism ; psychical time- extension versus physical flux; psychical finahty versus physical mechanism. I have tried further to show that these three capacities are merely three different expressions of that general character of the psychical or private aspect of experience which I accepted as the basis of its definition, viz., its es- sential unity and indivisibility as based upon the primacy of the structure or form of the system con- sidered collectively as a whole over the plurality of its elements considered distributively as an aggre- gate. We have now to take the second step in our 118 CONSCIOUSNESS AS ENERGY problem and to investigate the process in which the events of a psychosis are consequent upon physical events in the brain. II Consciousness from Without: Intensive Sensation and Kinetic Stimulus We are at the outset confronted with a certain postulate or assumption, adopted by the Cartesians and by almost all later philosophers. The assump- tion was as natural and excusable as it was false and mischievous ; unless it can be refuted any attempt to solve the psychophysical problem must appear futile. This momentous postulate is the expression of a twofold exaggeration of that dis- tinction between psychical and physical which has been described above. Direct experience together with profound insight into scientific method con- vinced Descartes that matter was fundamentally quantitative or spatial, infinitely divisible, and controlled by mechanical law, and that mind, on the other hand, was teleological, indivisible, and qualitative. In the first flush of enthusiasm over this true discovery it was falsely inferred to mean that matter was nothing but quantitative and that mind was nothing but qualitative. The result was a dual denudation of the physical and psychical orders. All true or non- quantitative qualities, i. e., all *^ secondary "' quxilities were removed from the \\M. PEPPERRELL MONTAGUE 119 material world and dumped bodily into the mind, that mind being at the same time and from a similar motive deprived of all real extension and real pres- ence in the physical world of its objects. And in place of two contrasting relational nexuses, ex- hibiting contrasting types of behavior, there en- sued the extraordinary conception of two separate realms of events, — a physical realm pre-empting all real space and over against this a psychical realm which not being in space was nowhere at all, though of course quite "real." The appalling dualism thus begotten speedily led all who could clearly realize its implications to abandon any conception of a causal relation between the two sundered halves of the universe. All true causal- ity involves a transfer of influence or energ\' from the causal agent to the patient on which the effect is produced. But energy cannot be transferred from somewhere to nowhere, and back again from the nowhere of the mind to the space of the brain and the physical world. Such a "transfer," if it could mean anything, would mean that energy was annihilated in sensation and created in voli- tion. It was the recognition of this implication that led quite properly to the doctrine of the con- servation of energy being invoked as an additional argument against any interaction of physical and psychical. Nothing was left but to describe the synchronous and thoroughly correlated occurrences in the two realms as a mysterious relation of "par- 120 CONSCIOUSNESS AS ENERGY allelism." And in spite of the growing demands of Darwinian biology on the one hand and of common-sense and direct experience on the other, psychophysical parallelism, which when properly interpreted means automatism or the epiphenomality of consciousness, stands to-day as the scandalous but irrefutable consequence of postulating a material world without qualities and a world of minds that lack spatiality and exist — nowhere. As I have elsewhere^ argued in detail against this postulate, I may confine myself here to a very summary statement of what seem to me to be its several invalidities : 1. Each man feels his consciousness to pervade not only his body but the outer space in which his objects appear. This immediate revelation in ex- perience of the spatially extended nature of con- sciousness is not and is not felt to be in the least incompatible with its intensive unity and indivisibility. 2. The fact that each consciousness feels itself to pervade the visible space in which its objects appear is not and is not felt to be incompatible with the equally intuitive conviction that that con- sciousness could never be visible or in any way accessible to the external perception of another ob- server. To the eye of such an external observer the space occupied by consciousness would always ' The Monist, January, 1908, " Are Mental Processes in Space ? " WM. PEPPERRELL MONTAGUE 121 appear filled with the purely physical objects of matter and motion. 3. The real presence in physical objects of qualities such as are perceived in them is in no sense incompatible with the true behef that such qualities are in themselves inefficacious in the pro- duction of physical changes, that they are each of them correlated with or inherent in the spatial and purely mechanical relations of material par- ticles, and that it is in these quantitative correlates of qualities that true explanations are to be sought. Suppose, now, that we are freed from the para- doxical antithesis of consciousness and space, — how does the psychophysical problem present it- self ? A physical influence or stimulus which though not lacking quality is primarily quantita- tive and accessible to the external sense of many observers is transmitted along a sensor}' nerve and appears to give rise to a sensation or psychical state which though not lacking in quantit}^ and spatiality is accessible to the internal perception of only one observer. TJiat this happens is an obvious fact easily verifiable in any experience and not to be got rid of by any metaphysical or methodological theory whatsoever. But can we conceive how it happens ? A clew to the answer is, I believe, to be found in a certain type of occur- rence in the physical world. When an elastic body collides with a fixed barrier, the motion of the body gradually decreases to zero and then begins 122 CONSCIOUSNESS AS ENERGY to increase again in an opposite direction up to almost its original amount. At the moment prior to the rebound there is no motion in any direction ; for before a reflected motion southward can begin, the incident northward motion must wholly cease. The motion in the world is not conserved in the sense of being the same in amount at every mo- ment of existence. But energy is supposed to be conserved in just this sense. Hence, energy is of two kinds, of which visible motion is one; and it is only the sum of the two phases that is constant. The energy which is not motion but into which and from which motion passes is called potential. Naturally, the nature of this invisible type of energy is a question of some interest. There are, I under- stand, three theories of its nature. (1) There is the theory that it is some sort of invisible motion (other than heat) of the particles of a body into which the molar motion is transformed. This appears untenable for the reason that precisely the same problem will necessarily recur in connec- tion with these particles, no matter how tiny they are made or how often we subdivide them. Two particles collide, lose their motions, and regain them in opposite directions. What becomes of the energy of these little motions during the moment of their redirection? (2) There is the theory that the kin- etic energy of elastic bodies prior to coUision passes at the moment of collision into nothing and comes out again from nothing quite fresh, and unchanged WM. PEPPERRELL MONTAGUE 123 in form or quantity. This is the view of potential energy that seems most in favor at present. Ac- cording to it, potential energy is really nothing but potential. It is in no sense actual, but is just the sheer possibility of a certain quantity of motion. In favor of this conception it might be said, I suppose, that potential energy is not and from its very nature cannot be perceptible to external ob- servers ; that it is consequently not actual in any intelligible sense. And again, that to consider it as actual would be, if not absurd, at least useless, for it is only measurable indirectly, in terms of the motion of which it is the promise. (3) There is finally the older view that potential energy is stress or force; that as such it is just as actual as the motion from which it has come, and into which it will pass; that it is "potential" only with respect to motion, and that motion might with equal propriety be called potential energy of stress. In favor of this third view it might be said : I. That it has never been empirically refuted, is still held by some physicists and has in the past been held by men of the insight of Faraday. II. That potential energy, though not visible or externally perceptible, is nevertheless definitely and directly perceivable internally or by participation in it through what is inaptly called the "muscular sense " ; and that it is absurd to speak of the stress quality revealed by this internal or muscular sense as being less real or more anthropomorphic than 124 CONSCIOUSNESS AS ENERGY the motion quality revealed by the visual sense. III. That energy in the form of stress, while most easily measurable in terms of the motion which it will yield is nevertheless capable of as precise mathematical formulation as that motion itself, viz., as mas, or the product of the mass, the accel- eration and the space through which that accelera- tion obtains. In short, the third view, according to which force is a real phase of energy, is, first, logically necessary in order to avoid the unthink- able paradox of a real motion passing into and issuing from nonentity ; it is, second, a direct revela- tion of experience; it is, third, capable in its own right of mathematical symbohzation. When we formulate kinetic or motion energy as J m-v^, we recognize it to be the product of the mass and the integral (with respect to velocity) of the velocity. In the same way potential energ;y' formulated as mas may be recognized as the derivative (with respect to time) of the velocity. Acceleration is the derivative of the same func- tion of which J i;^ is the integral, viz., the function ds' dt * Of course equal quantities of the potential energy denoted by m • a • * may differ in kind according to the relative values of the three factors, (m) (a) and («). And leaving aside variations in the mass factor, we should have two types of potential energy ; one would be of the type instanced by a sys- tem of widely separated bodies attracting one another by the force of gra\dty, and the other of the type presented by a compressed spring. In the former type a relatively small acceleration, (a), extends through a relatively great space, («), while in the latter a relatively great acceleration (a) acts through the relatively small space («) occupied by the spring; the product {a-s), however, being the same in both cases. WM. PEPPERRELL MONTAGUE 125 If one place his hand between a fixed spring and a body moving uniformly into collision with it, he can get as clear and direct a perception of this continuous transfer of motion into a stress which is felt to be homogeneous though not identical with it, as he can of any other phenomenon whatever. And the mathematical homogeneity of ^ m • if and mas accords with this immediately felt homogeneity of motion and stress. What is the a priori warrant for believing that reality can con- tain only integrals of velocities and not their deriva- tives ? Of course stress from its very nature can never be revealed to the visual sense, while motion can. But is it not an over-enthusiasm for the in- strumental excellence of the retina to regard it as having a monopoly in revealing the qualities of the actual ? To be consistent in carrying out this apo- theosis of the retinal and condemnation of the mus- cular sense, we should have to define the inertia and the gravitational property of mass itself in terms of the motion with which they can undoubt- edly be correlated. But I cannot see how such a reduction of mechanics to a geometry of the motion of shadows or visible forms would possess any ex- clusive ontological validity, even if Professor Karl Pearson be right as to its superior methodological elegance.^ Let us assume, then, that potential energy or stress is as real as kinetic energy and that * Cf. "The Grammar of Science," especially chapters VI and VITI, in which the reality of force is attacked as an exploded superstition and even mass is defined exclusively in terms of motion. 126 CONSCIOUSNESS AS ENERGY consequently we should speak of an intensive rather than of a potential phase of energy. I wish now to point out certain very curious resemblances between this intensive energy and that which from the point of view of introspection we defined as the psychical. The first and perhaps the most striking of these resemblances is the essential invisibility or privacy which characterizes both energy in its intensive phase and also the non-physical elements of con- sciousness. Leibniz reminds us that the most pow- erful microscope could not, if applied to the brain of a fellow-man, disclose anything of his thoughts and feelings. We may remind ourselves that the most powerful microscope, if applied to a com- pressed spring or to the space of a magnetic or of a gravitational field, would be equally unable to dis- close the stresses therein. As objects of external or visual perception, potential energy and the psy- chical are both of them non-existent. We can feel stress only by participating in it, just as we could feel our neighbor's toothache only by participating in it through some such inter- organic, nerve-graft- ing device as Professor Pearson has suggested. From the external point of view, potential energy and my neighbor's toothache are ejects which I must postulate in order to explain the otherwise inexplicable hiatuses in the series of visual percep- tions which originate from and terminate in them. Secondly, both consciousness and intensive en- WM. PEPPERRELL MONTAGUE 127 ergy seem to pervade the space of the things they influence, and in this both resemble matter. But in thus extending in space they each of them seem to forfeit thereby no whit of their pecuHar unity and indivisibihty, and in this both of them differ from matter. You cannot imagine your consciousness, although it pervades the space of its perceptual objects, being divided into pieces or composed of them. No more can you imagine dividing into sep- arate pieces the elastic stress that pervades a spring or the gravitational stress that pervades the plane- tary system. Thirdly, we pointed out in the first section of this paper, how, from the essential primacy of unity over divisibility in a psychical system, there followed that curious conformity in the behavior of its ele- ments to the structural form of the system as a whole which was manifested in the teleological na- ture of psychical processes. Now, consider the behavior of a swarm of moving iron filings when they come within the field of a magnet. Prior to their advent in the field, each is in its existence rela- tively autonomous as respects the others, though subservient to the impulses received in actual im- pact with them (mechanism). Once within the magnetic field, however, the filings forget, as it were, their individual strifes, and each in relative indifference to the bumps of its fellows assumes tlie position demanded of it by the structure of the field into which it has come. The formless chaos 128 CONSCIOUSNESS AS ENERGY of filings gives place to the ordered system which so surprisingly incarnates, or bodies forth to the eye, the invisible and indivisible lines of magnetic stress. Fourthly, the conditions under which a stimulus is followed by a sensation happen also to be conditions under which energy passes jrom a kinetic into an in- tensive phase. Perceptions are presumed to arise synchronously with the redirection in the central nervous system of afferent currents into efferent channels. When this process of redirection is pro- longed by reason of the many conflicts with the cerebral association currents induced by the affer- ent intruders, then the consciousness is prolonged, keen, and complex. When, on the other hand, by reason either of innate adjustments or of long practice, the journey through the central labyrinth is quick, smooth, and direct, then the consciousness, if present at all, is simple, faint, and brief. Note that the condition for motion passing into stress is always that it meet with some obstacle by which it is redirected, and that the proportion of the energy that becomes potential depend on the degree of change in the motion's direction. If a ball be thrown perpendicularly against a wall, the whole of the incident motion must disappear before the reflected motion can ensue. But if it be thrown obliquely then only so much of the motion can pass into stress as is equal to that imaginary compo- nent of the motion, which is normal to the wall. Several observers might conceivably follow with WM. PEPPERRELL MONTAGUE 129 their eyes the nerve current as it traversed the circuit from sensory origin to motor terminus, and at the very moments when the whole or some part of its kinetic energy did, by reason of a change in its direction due to the interference of rival currents of cerebral origin, disappear into an intensive or potential phase : — at those same moments there would be reported a psychical fact accessible only to the observation of the one person through whose brain the stimulus was passing. " When a thing looks like a frog and acts like a frog and croaks like a frog, we call it a frog." And on the strength of the four fundamental resem- blances described above I propose as a possible solution of the psychophysical problem the fol- lowing theory : WJiat 7, jrom within, would call my sensations are neither more nor less than what you, from without, would describe as the forms of potential energy to which the kinetic energies of neural stimuli would necessarily give rise in pass- ing through my brain. We do not as yet know enough about the nature of the neural stimulus or "current" to form a sat- isfactory conception of the manner of its transfor- mation into the potential phase. If it be some form of vibration or ordinary wave motion, then the change is of the same sort as that undergone by a beam of light in changing from the incident to the reflected path. If on the other hand the nerve "current" be electrical in its nature, resembling, 9 130 CONSCIOUSNESS AS ENERGY as has recently been suggested, the relatively slow progress of energy along a telegraphic cable, then its transformation into potential energy might per- haps be likened to that wrought by an electro- magnet in which a portion of the energy of the electric current is drained off into the potential form of a magnetic stress in the surrounding field. I hasten, however, to answer an objection which is obvious and which might appear crushing. We know, it may be said, what force is — at least if we choose, as I have done, to give that name to the quality revealed by the muscular sense. And we know what a sensation in general is. They are plainly different, and to identify one with the other is sheer silliness. It is like saying with the materi- alist that a sensation is a mode of motion. To iden- tify odor with color, or pain with sound, would be futilities of the same kind. To this objection two answers may be made. First, it will be remembered that when we aban- doned the modern dualistic postulate of a non- spatial consciousness, we abandoned also its equally vicious correlate — the postulate of an abstract physical world made up of mere quanti- tative relations and lacking all the specific natures or secondary qualities that are correlated with those relations. Now, if we return to the older view of common-sense, according to which every physical thing and every motion or stimulus pro- ceeding from it has correlated with it a specific WM. PEPPERRELL MONTAGUE 131 nature — not a substantial form but rather a form inliering in the motion that carries it — then the change of the kinetic energy of the stimulus into the potential energy of the sensation will not be a mysterious change of sheer quantity into sheer qual- ity, but only the change into a qualitative form of stress of a similarly qualitative form of motion. So what we perceive as mere undifferentiated stress is simply the general "substance" of sensations, i. e., the basic and generic quality common to them all, the different degrees of which are felt as the differences of intensity to which every sen- sation is alike susceptible. Stress as psychical substance would thus be related to particular sen- sations precisely as extended matter is related to particular objects. All physical objects are ex- perienced as having the general quality of ma- teriality in addition to the specific qualities by which they differ. But, secondly, it may also be said in explanation of the difference between mere stress and the rich variety of our feelings and sensations that what we have so far been considering as potential energy and formulating as mas is only one, and that the simplest and lowest of the intensive phases into which kinetic energy may pass and from which it may come. Acceleration is only the first deriva- tive of velocity with respect to time; and if an energy quantum can pass from the extensive phase represented by the integral of a velocity (J ^^) 132 CONSCIOUSNESS AS ENERGY into the intensive phase represented by its first derivative ( — ), it would seem that it might on occasion pass equally well into any or all of the infinity of higher phases of intensive energy symbolized by the series of velocity derivatives of higher order than the first, viz., (d^v d^v dM) dy \ \dP' dP' di" ' ' ' ' dt'' ' ' ' J The qualities denoted by these higher derivatives would have no place or meaning in the physical world except as higher orders of the potentiality of motion, but they could well exist as actualities in the intensive sphere of the psychical. They would constitute those tertiary contents of con- sciousness which even the most realistic of realists can hardly imagine to exist apart from some awareness of them. I refer to such things as love, envy, fear, and hate, and the whole inexhaustible host of the finer forms and nuances of these. And here, then, in the answer to what might have seemed a fatal objection, we find a fifth fundamental resemblance between the psychical and the inten- sive phase of energy with which our theory seeks to identify it. Any given psychosis con- tains only a tiny fraction of the totality of physi- cal events, but the psychical in general has the capacity not only for all perceptible physical objects but also for the whole assemblage of thoughts and WM. PEPPERRELL MONTAGUE 133 feelings about those objects. This consideration alone would be suflBcient to disprove a parallelism of the "double-aspect" type. For the assemblage of possible psychical elements or forms of inten- sive energy denoted by the higher derivatives is to the assemblage of possible physical events or kinetic energies denoted merely by the first order of integrals as a multi-dimensional manifold is to the uni-dimensional manifold that forms the lowest and Hmiting of its "cross-sections." Or to express the same thing in another way, we can say that the physical world of public objects is the indefinitely extending and ever-present surface of contact from which originate and in which terminate the series of intensive or psychical events, these latter being private and insulated from one another except in so far as they participate in the common physical order. Or, finally, we might liken the relation between physical and psychical to that obtaining between the one kind of wealth embodied in money, and the totality of objects of wealth which are being constantly interchanged and mutually evaluated through the agency of that money as a universal medium of circulation. We found at the outset of this investigation that the problem of defining consciousness would prop- erly involve the solution of three subsidiary prob- lems : (1) The definition of the psychical as it appears to introspection or from within, a distinc- tion between psychosis and hylosis as directly 134 CONSCIOUSNESS AS ENERGY presented in the experience of each of us. (2) The definition of consciousness as it appears or is in- ferred from without, as centering in the brain of another man and constituting the essentially in- visible origin and terminus of his nerve currents ; the consideration of which is the psychophysical problem of the relation of stimulus to sensation. (3) A comparison of the properties of psychical systems with the properties of living systems that would throw light on the bio-psychical problem of why it is that consciousness must have as its matrix a growing and reproducing organism of protoplasmic matter. I have endeavored in the first and second sec- tions to present a conception of consciousness as energy that seemed to me to meet the demands of the first two of the three problems just named. The third problem must be omitted, though its consideration, would, I hope, serve to supplement and in some measure to clarify and concretely corroborate what has here been said. PERCEPTION AND EPISTEMOLOGY PERCEPTION AND EPISTEMOLOGY By Frederick J. E. Woodbbidge What perception is," says John Locke, "every one will know better by reflecting on what he does himself, when he sees, hears, feels, etc., or thinks, than by any discourse of mine. Whoever reflects on what passes in his own mind cannot miss it. And if he does not reflect, all the words in the world cannot make him have any notion of it. This is certain, that whatever alterations are made in the body, if they reach not the mind ; whatever impressions are made on the outward parts, if they are not taken notice of within, there is no percep- tion. Fire may burn our bodies with no other effect than it does a billet, unless the motion be continued to the brain, and there the sense of heat, or idea of pain, be produced in the mind ; wherein consists actual perception." ^ Psychologists since Locke have often thought of perception more narrowly, but his words still serve to point out the different attitudes towards the fact that to know our world we must perceive and re- flect upon it, which have been conspicuous in mod- ' "Essay concerning Human Understanding," edited by A. C. Eraser, Vol. I, p. 183. 137 138 PERCEPTION AND EPISTEMOLOGY ern inquiries into the subject. They suggest that perception is a process which we may examine by considering what we do when we see or hear, and that it is a content, a result, which we may, conse- quently, consider as such, and about the nature and relations of which we may inquire. It is with these two attitudes towards perception that this paper is primarily concerned, so far as the problem of knowledge is affected by them. Inquiry into what we do when we see involves us naturally in researches into those physical and physiological processes which Democritus seems to have been the first to formulate with any great amount of completeness. We are led to recognize sources of stimulation, media for the transmission of the stimulus, organs for its reception, and reac- tions of the individual possessing the organs. In a particular case, as in that of seeing, we try to isolate a particular process and discover how it is related to other similar processes. In short, we inquire into the mechanism of perception. We deal with factors, processes, and quantities sup- posed to be known or ascertainable. Stimulus, medium, and organ, for instance, are distinguished as identifiable factors in one continuous sphere of investigation. Any doubt about their existence, their character, or their mode of operation tends F. J. E. WOODBRIDGE 139 to vitiate and obscure our understanding of the mechanism we are trying to discover. Further, our procedure is not speculative, but experimental. So far as possible we measure the stimulus, the rate of its transmission, and its effect. We do what can be repeated by others, because to others our method is intelligible and the means of repeti- tion are at their command. Should we engage in mere suppositions, admit tliat the stimulus, for instance, were not something given with which we can experiment, but something assumed to account for certain facts, our laboratories might well be closed, and the mechanism of perception left for anyone to conceive according to his preferences or whims. But it is precisely such admissions which we do not make. We may admit that other points of view may lead to a revision of the ultimate significance of our results, but we never willingly admit that the method and the factors of our investigation are not intelligible, clear, and unambiguous. Still further, we are quite unwilling to set any arbitrary limit to the extent to which inquiries of this nature may be successfully pursued. What- ever limits we discover we set down to our igno- rance, to our lack of appropriate instruments, to our failures, but not to any restraints due to the method we employ or to the nature of the factors with which we deal. We may characterize certain results of perception as illusions, but such a char- 140 PERCEPTION AND EPISTEMOLOGY acterization does not deter us from inquiring into their mechanism in precisely the same way as we inquire into the mechanism of those results we call normal or real. We may even ask, as Locke suggests, what we do when we think, and admit that the only bar to our discovery of the mechan- ism of thought is a temporary ignorance which at any moment may be removed. In general, then, perception as a process defined broadly in terms of Locke's general definition of it is a process open to experimental inquiry in an intelligible and un- ambiguous manner, an inquiry which can be re- peated, checked, and verified by anyone who takes the pains to do so. The result is a concrete body of knowledge steadily increasing in extent and definiteness, and gradually accumulating solid information about the world in which we live. No one naturally fails to grasp its aim, its method, or its import. No one finds confusion in it unless he departs from the point of view from which it is instituted and proceeds to estimate it according to standards and criteria other than those which are employed in building it up. Similar observations may be made about the results reached when we take the other attitude towards perception; when, that is, we regard it as a content or product. Naturally we are now no longer concerned with the process or mechanism by which the content is attained, but solely with the facts which are the outcome of that process. F. J. E. WOODBRIDGE 141 When we see, certain things are done, but some- thing also is seen. That which we see we now call a perception, and in general we may use the term "perceptions" to denote whatever may be the objects of our regard. Now these perceptions we may enumerate. We may classify them. We may analyze them into such elements as we may be able to discover. We may find out how these elements are related to one another, how they may be combined, how they modify one another. About the combinations w^e may make similar in- quiries. In short, we may institute a wide range of investigations into the things we perceive with- out departing from the point of view which takes these things simply as the objects of our regard, and without asking how we perceive them. Such inquiries may be as free from speculation and mere assumptions as those we make into the mechanism of perception as a process. They may be equally as experimental. They may be kept true to their point of departure and yield concrete bodies of knowledge of great value. The results attained are accessible to anyone who cares to review them. The methods and experiments by which they are attained can be repeated, they can be checked and verified at any point desired. We find no ambiguity or confusion in the knowledge they afford us so long as we do not depart from the point of view from which these particular in- quiries are instituted. 142 PERCEPTION AND EPISTEMOLOGY When we speak of those bodies of knowledge which result when we regard perception solely as a content or product, we are apt to think prima- rily of analytic and descriptive psychology. But it is clear that they may not be so restricted. They comprise, in fact, by far the greater part of what we know. The astronomer, the biologist, the chemist, the historian, the student of literature — to mention only a few instances — are all en- gaged in increasing our knowledge of what our perceptions are and how they are related to one another. Their studies are not prefaced by an ex- amination of how we perceive. They take their material as so much given stuff, and then proceed to tell us what, when so taken, they discover it to be. If they are invited first to examine the mechan- ism of perception, they regard the invitation as im- pertinent and irrelevant. They have found such an examination to be unnecessary, and so believe that they can rightfully neglect it. Even when their attention is called to the fact that the processes by which we perceive have important bearings on what we perceive, they find that their observations can be controlled by well-known methods, by putting them, for instance, in the context which theories of probability, based on a number of ob- servations, afford. They can thus make their observations approach any degree of theoretical accuracy desired. We should, doubtless, count among the bodies F. J. E. WOODBRIDGE 143 of knowledge which result when perception is re- garded as a product, more than histor}^ and the greater part of natural science. For, naturally, we may make these bodies of knowledge themselves objects of investigation, asking after their general constitution, the manner of their building up, and the grounds which lead us to view them with confidence. These are problems with which logic is concerned. How far they constitute the full extent and nature of logical theory may be left for the present purpose undecided. But it is clear that a logic which would deal with them successfully would be a very comprehensive science. When we should know how different bodies of knowledge differ, how far these differences are due to mate- rial, to method, and to aim, when we should know how these bodies of knowledge are built up from what we perceive, and with what degree of confi- dence they may be entertained, we should then have largely satisfied the demands which our interest in logic occasions. Such a logic, like the bodies of knowledge it reviewed, would be experimental, it would itself be capable of review by anyone in- terested without involving the reviewer in ambig- uous assumptions. It would simply say to him, Such and such is the case with these bodies of knowledge; examine them for yourself and you will find it so or be able to indicate where inaccu- racy exists. It is quite inconceivable that such a logic could afford matter for debate rather than 144 PERCEPTION AND EPISTEMOLOGY for investigation. It would hardly be called by the names of those who worked at it, or be the posses- sion of a "school" or a "philosophy." It would constitute a body of common knowledge which investigators could enlarge and thereby enlarge their own reputations. In proportion as it kept clear its title to common knowledge, admitting review and repetition of experiments at all points, it would be free from ambiguity and confusion. It seems clear, further, that the point of view under consideration could yield a metaphysics which, like history, the sciences, and logic, could claim to be experimental and constitute a body of common knowledge. For it may well be that the things which we perceive, when taken in as com- prehensive totals as we can grasp, present certain general features of character and connection which we tend to disregard or overlook when the same things are taken less comprehensively and com- pletely. Such characters and connections have been historical themes of metaphysics. When looked for in the world of concrete perceptions they may not constitute all that historical metaphys- ics has been pleased to investigate, but the experi- mental restriction cannot obscure the magnitude or importance of the body of knowledge which might result. For, most assuredly, if there are gen- eral types of existence among the things we per- ceive and general types of connection, the clear definition of their characters and modes of opera- F. J. E. WOODBRIDGE 145 tion could not fail to be of importance, or to afford problems of ceaseless and varied interest. A meta- physics of the kind suggested would admit of natural growth from generation to generation, be- cause it would be knowledge of the kind that pur- sues a common road and that can be repeatedly checked and reviewed. Bodies of knowledge of the kind described by no means constitute the sole results of our inquiries. We seek to supplement them by hypotheses, theo- ries, and philosophical speculations, but we find our vision of the world grows clearer thereby only as these supplementations are genuinely such. The moment they lead us to deprive the results of careful research of their natural character and purport, these results become ambiguous and misleading. We no longer remain clear as to the information they in- tend to convey. When, for example, Huxley tells us that " a sensation is the equivalent in terms of con- sciousness for a mode of motion of the matter of the sensorium," and that the assumption of the ex- istence of matter is a "pure piece of metaphysical speculation," ^ our thoughts on the subject of sen- sation become confused instead of clear. It seems unjust to his careful investigation to conclude that a sensation is a certain kind of equivalent for some- thing the existence of which is a pure piece of meta- physical speculation. Indeed, if such is to be the * " Hume : with Helps to the Study of Berkeley." New York : D. Appleton & Co., p. 317. 10 146 PERCEPTION AND EPISTEMOLOGY outcome of our study of sensation, that study is hardly worth while. It does not clarify the thing it intends to clarify. It obscures it and makes it unintelligible. Thus it is that speculation only con- fuses experimental knowledge when, by depriving our results of their evident import, it fails genuinely to enlarge or supplement them in the direction in which they naturally point. Again, it is only by being such genuine enlarge- ments or supplementations that speculation can be controlled and preserved from mere idiosyncrasy. As pragmatism has now abundantly taught us, with fresh insistence on a piece of wisdom long familiar, speculations which can own no checks or make no differences in the world with which we directly deal are matters which it is idle to seek to verify. We may accept them, not because they give us information about our world continuous and ho- mogeneous with what we naturally acquire, but be- cause of their inherent interest or their consonance with our moods. Whether, therefore, we regard perception as a process the mechanism of which we are to discover, or as a product comprising the realm of what we perceive, it is evident that we may sketch out extensive bodies of knowledge consistently and unambiguously pursued from these two points of view. Even if the points of view differ, the resulting bodies of knowledge are of the same general char- acter. They are what I have called experimental. F. J. E. WOODBRIDGE 147 And by that I have meant that the elements, the terms, the relations, the connections, the qualities, the quantities — or whatever terms we may choose by which to designate the various things we study — can all be identified by anyone who wishes to identify them, and that whatever is said about these things can be tested by anyone who will refer to the things in question. The bodies of knowledge are not mere possibilities which we may some day realize, but they are actual bodies of knowledge already existing in various stages of progress. What I would particularly emphasize about them is their experimental character and the fact that they are accepted by the vast majority of people at their face value, as measurably accomplishing the thing they set out to do. That they are so accepted will, probably, be gen- erally admitted. When we are told that under specified conditions objects excite certain disturb- ances in the medium between them and our eyes, and that our eyes are affected by these disturb- ances in various ways, that retina and nerve are thereby stimulated, and that consequently we see, we tend to believe what we are told. AVhen we are told that the medium is the ether, we may have difficulty in comprehending just what the ether is, but w^e tend to believe that there is such a thing or something like it which we might understand better with increased knowledge. We tend to be- lieve these things just as we tend to believe the 148 PERCEPTION AND EPISTEMOLOGY historian when he tells us that the Pilgrims landed in 1620 A. D. Indeed, we naturally regard state- ments about the ether, about the processes and results of perception, and statements about the Pilgrims, as statements of the same general kind purporting to inform us about the conditions and happenings in the world in which we live. Simi- larly, we incline to accept the statements of the sciences for just what they purport to be: that there is such a substance as oxygen and that it combines with other substances in certain ways ; that these substances may be atomic in structure or of a structure more complex ; that living beings vary in certain ways and preserve an amount of continuity in their succession ; that the natural his- tory of the world is, in large measure, a genuine account of what has happened. In short, what- ever knowledge is of the experimental kind we take its deliverances as probably correct informa- tion about the things with which it deals. This habit of mind is by no means incompatible with the liberal recognition that we know but little and that the little we know is doubtless subject to re- vision. But we naturally hold tenaciously to that little until the need of revision has become appar- ent. The revised knowledge is, however, the same in kind as that which it supersedes. F. J. E. WOODBRIDGE 149 II AMiether we regard perception as a process or as a content, concrete bodies of knowledge result pur- porting to give us approximately correct informa- tion about the world in which we live. Yet it has been repeatedly insisted that just because these two attitudes towards perception exist informa- tion about our world cannot ultimately be taken at its face value and with its natural import. For, it is urged, if we mean by perception as a content that which we immediately perceive, it is evident that, in the last analysis, perception is given to us only as a content. We may, of course, still speak of examining into the processes of perception and even of experimenting upon them, but it should be evident that these processes, so far as we directly attack them, are themselves perceptions, they are what we immediately perceive, they are contents. How, then, can we be justified in regarding them as the real processes which precede contents and result in perceptions ? On the other hand, if we cut the contents wholly off from their supposed processes, how can we be justified in longer be- lieving that they, with the bodies of knowledge built directly upon them, afford us reliable infor- mation about our world ? Are we not confronted here with the problem of knowledge in its most serious and fundamental form, and confronted 150 PERCEPTION AND EPISTEMOLOGY with it in a manner requiring a procedure and point of view in marked contrast with the pro- cedure and points of view which have given us our bodies of positive knowledge? Do we not need a theory which may free us from a situa- tion which, otherwise, must remain ambiguous and paradoxical? We have in these questions one way of stating the central problem of modern epistemology. More attention has been paid to the soundness of the solutions which have been offered of this problem than has been paid to their success in modifying positive knowledge and in giving us increased reliable information about our world. If, however, we do not raise the question of their validity, but ask rather concerning their impor- tance for the bodies of knowledge which are steadily built up in the ways indicated in the early para- graphs of this paper, we are confronted with the fact that they have not modified these bodies of knowledge in any essential particular, nor sup- plemented them in any continuous and homogene- ous manner. Their efficacy has exhibited itself primarily in modifying our personal estimate of the significance of what we know. Some illustra- tions of this result may reinforce the general statement. Professor Karl Pearson's characterization of the concepts of science as conceptual shorthand has, as is evident from his " Grammar of Science," F. J. E. WOODBRIDGE 151 an epistemological basis. There may be no atoms and no ether. Indeed, he conceives their existence to be relatively an unimportant matter. The im- portant matter is whether they, as conceptual shorthand, help us to resume the routine of our perceptions. But it is clear, none the less, that scientists attempt to discover the constitution of the ether, the weight of atoms, their structure, and their relations to one another. I say they attempt to discover these things, they do not attempt simply to conceive them. The acceptance or rejection of Professor Pearson's epistemolog}' does not appear to affect their methods of research or the formula- tion of their results. He may lead us to believe that an epistemological estimate of the value of science is a very important matter, but it seems to be im- portant not because it makes for a better or a more accurate science, not because it increases our suc- cess in using the results of research in industry and the arts, but because it tends to modify our personal estimates of the ultimate significance of knowledge. The "Grammar of Science" con- tributes, undoubtedly, to the methods and results of science, but its epistemology contributes not to their enlargement, but to their spiritual evaluation. It leads us to reflect on the importance of the proper estimate of science for social progress and citizenship. As a second illustration, I take the following paragraph from Professor H. Poincare's "Value 152 PERCEPTION AND EPISTEMOLOGY of Science**: "Does the harmony the human inteUigence thinks it discovers in nature exist out- side of this inteUigence ? No, beyond doubt, a reahty completely independent of the mind which conceives it, sees or feels it, is an impossibility. A world as exterior as that, even if it existed, would for us be forever inaccessible. But what we call objective reality is, in the last analysis, what is common to many thinking beings, and could be common to all; this common part, we shall see, can only be the harmony expressed by mathematical laws. It is this harmony then which is the sole objective reality, the only truth we can attain; and when I add that the universal harmony of the world is the source of all beauty, it will be under- stood what price we should attach to the slow and difficult progress which little by little enables us to know it better." ^ Even if these words contain the proper estimate of the value of science, even if it is true that the only genuine objective reality is a harmony which does not exist outside of the intel- ligence which discovers it and is yet common to many thinking beings, we find thereby no new ways to enlarge or correct our positive knowledge about the world. We may be freed, as Professor Poincare suggests, from a certain fear of scientific truth which might otherwise oppress us. We may have our spiritual vision broadened. But the prog- ress of science does not seem to be affected by such ^ Popidar Science Monthly. Vol. LXIX, p. 196. F. J. E. WOODBRIDGE 153 services except in so far as they help to remove our prejudices or make us enthusiastic. If we turn to the writings of those who are more exclusively epistemologists, the same general con- clusions will be forced upon us. How repeatedly we have been told that epistemology does not dis- turb the ordinary processes of knowledge ! How naturally philosophers have been led to commend it for its effects on character ! "If, therefore," says Berkeley, "we consider the difference there is be- twixt natural philosophers and other men, with regard to their knowledge of the phenomena, we shall find it consists, not in an exacter knowledge of the efficient cause that produces them — for that can be no other than the will of a spirit — but only in a greater largeness of comprehension, whereby analogies, harmonies, and agreements are discovered in the works of nature, and the particular effects explained, that is, reduced to general rules." Again he says: "From what has been premised, no reason can be drawn why the history of nature should not still be studied, and observations and experiments made; which, that they are of use to mankind, and enable us to draw any general conclusions, is not the result of any immutable habitudes or relations between things themselves, but only of God's goodness and kind- ness to men in the administration of the world." ^ Illustrations from certain contemporaneous phi- ^ "Works," Eraser's eclitioa, 1901, Vol. I, pp. 815, 317. 154 PERCEPTION AND EPISTEMOLOGY losophers might also be cited to indicate that in their opinion the great aim of philosophical inquiry into the foundations of knowledge is not to rectify or homogeneously to supplement the results of positive knowledge, but to afford us a spiritual estimate of these results. By considering episte- mological speculations we are led to reflect on our relations to the absolute. Considerations like the above point to the con- clusion that the service which epistemology renders is not logical, but moral and spiritual. It affords us, to use the expression with which Professor Santayana describes religion, "another world to live in," a world where it may indeed be good to dwell now and then, but which is so different and remote from the world where perception is a fact and a process for investigation that the problem of perception receives thereby no genuine solution. In terms of that other world we may describe per- ception in ways endeared to epistemology, but when we seek information about what we perceive and how we perceive it, we return to the world of positive knowledge. Should we ask if this informa- tion is correct, we should find no answer in that other world. It would appear, therefore, that the problem of the relation between the content and the process of perception is not clarified by episte- mology. Possibly it is a problem which does not involve the question of the nature and validity of knowledge at all, for it may well be that the rela- F. J. E. WOODBRIDGE 155 tion between content and process is not a cognitive relation. In spite of what appears to be its logical irrele- vancy for all bodies of positive knowledge, episte- mology, it may be urged, can hardly be dismissed for that reason. The processes of knowledge, studied as empirically and experimentally as you please, may occasion problems the solution of which may force us to recognize that there is a region of philosophical truth different from what positive knowledge reveals and beyond it, a region that forms indeed a supplement to that disclosed by science, but a supplement to be reached by other methods. That other world to live in may not at all be damaged by the recognition of it as another world; it may, rather, thereby receive added importance. If we are actually forced by the peculiarities of experience to frame a theory in the light of which we may scrutinize the truth of the bodies of knowledge we build up directly from the facts of life, we ought, no doubt, to sub- mit to such pressure and do the best we can in the way of such a theory. Furthermore, it may appear arbitrary and high-handed to claim that episte- mology itself is not built up directly from the facts of life, or that it is without experimental warrant. The facts of experience justify it, one may claim, and make it necessary. If its development leads us radically to revise our estimate of the results of positive knowledge, and to find in them a signif- 156 PERCEPTION AND EPISTEMOLOGY icance deeper than what they obviously disclose, is it not irrelevant to reply that epistemology does not alter the methods of positive knowledge or enlarge the content of history and the sciences in any continuous and homogeneous manner ? The realist may clamor for the recognition of the fact that all philosophy can do is to tell us in the most comprehensive way what we have found our world really to be, but the idealist can always retort that he has found our world to be precisely that which his own idealistic epistemology has disclosed. The clamor and retort do not, however, advance our knowledge. Yet I believe that the student who is interested in recording the results of modern intellectual inquiry is warranted in upholding the conclusion on which this paper has, thus far, insisted. We build up directly from considering the processes of perception, and also the results of those processes, vast bodies of knowledge without seeking any epistemological warrant for our procedure. We may build up an epistemology also, finding our warrant for so doing in matters which the bodies of knowledge referred to designedly and systemati- cally neglect, and be led thereby to scrutinize the truth of our positive knowledge from the vantage ground whither epistemology has carried us. But if we ask what actual service this scrutiny performs, we seem compelled to answer that the service is not logical, but moral and spiritual. It does not F. J. E. WOODBRIDGE 157 modify knowledge. It modifies character. It does not give us new or increased information about our world whereby that world may be more effectively controlled. It gives us rather considerations the contemplation of which is more or less satisfying to the spirit. Ill Such a situation is provoking. It has given rise to noteworthy systems of metaphysics which may serve to explain why the bodies of positive knowl- edge and epistemology have so little mutual rele- vance, and appear, nevertheless, to be natural and inevitable intellectual products. But the question I would raise here does not primarily concern these systems. It concerns rather the initial step which carries us to them. I should like to ask whether, as a matter of fact, the difficulties to which the theory of perception gives rise demand an epistemological solution. In other words, does the fact that the processes of perception result in contents which alone we can be said to perceive necessitate the question of the validity of what we know ? Can the problem of perception be intel- ligibly defined as a problem of cognition ? It has been quite generally assumed that we must ulti- mately define it as such a problem even if by so doing we become unintelligible, concluding that the content of perception is subjective because it is other than and subsequent to an objective proc- 158 PERCEPTION AND EPISTEMOLOGY ess which produces it, and then concluding that we must question or reconstruct the objectivity of the process because the only means by which we know it is the content. It is that assumption which gives point to the question whether we perceive things as they really are and which makes the claim that knowledge should be taken at its face value as a natural product appear so violent to many minds. Until this assumption is reckoned with we can hope for little clear appreciation of differences of opinion. I propose a general exami- nation of it here in the hope that I may at least suggest that its claims are far from final. "Fire may burn our bodies with no other effect than it does a billet, unless the motion be continued to the brain, and there the sense of heat, or idea of pain, be produced in the mind; wherein consists actual perception.'* From the truth of this state- ment few would naturally dissent. It contains, however, a formulation of the relation between the mechanism and the result of perception which is ambiguously sustained by the facts. It is evi- dent that unless the motion be continued to the brain we do not perceive the burn. But it is not evident in the same way that the sense of heat or idea of pain is produced there in the mind by the continuation of that motion. As has been repeat- edly maintained, we can follow that continuation of motion pretty far and the farther we follow it the more we grow convinced that we should not. F. J. E. WOODBRIDGE 159 could we follow it completely, ever come upon the sense of heat or the idea of pain. We are reasonably convinced that without sense-organs, nerves, and brain, we should never perceive the world as we do perceive it, but the more completely we understand organs, nerves, and brain, the less we think of ever discovering in them that world of varied objects and events. Now this fact has led, as it led with Locke, to the assumption that, there- fore, the world which we perceive cannot be con- tinuous and homogeneous with the process by which we perceive it. That world must be of a nature quite different, a world of "ideas," of "states of consciousness," a mental world, in short, the relation of which to the world in which the process occurs we must now speculate about and construct an epistemology to explain. The disparity, however, between the world which we perceive and the world where the processes of perception occur, tends to vanish on close examina- tion. When once perception as a content is styled "idea," many minds, under the logical restraint of such ambiguous propositions as " the idea of weight is not heavy" and "the idea of length is not long," have violently robbed "ideas" of the qualities they rightfully possess. What we perceive may be styled "ideas," but the name ought not to ob- scure the fact that some of these "ideas" are actually red and green, others sweet and sour, others noisy, others too heavy to be lifted, others 160 PERCEPTION AND EPISTEMOLOGY of measurable length. Were they not such, it is clear we should never speak of such qualities or seek to discover their causes. Epistemologists have struggled over the question of the relation of mind to matter, and idealists have insisted that matter is, after all, mental, but the obvious fact is that "states of consciousness" when made to include all that we perceive, do, some of them at least, possess the qualities which have been invariably ascribed to matter. Epistemology has done much to obscure this fundamental fact. Berkeley asks : " What do we perceive besides our own ideas or sensations .'* and is it not plainly re- pugnant that any one of these, or any combination of them, should exist unperceived .? " ^ Clearly it is plainly repugnant and a manifest contradiction to suppose that perceptions are not perceptions, but is matter thereby destroyed ? Is not what we per- ceive red ? Is it not a deafening noise ? Of those two things we perceive is not one longer than the other ? Has not what we perceive momentum and weight ? Is it not, then, plainly repugnant to conclude that the contents of the mind are, all of them, immaterial ? Even, then, if we assume that the world we per- ceive is not continuous with the process by which we perceive it, it is a world not so very unlike the world in which the process takes place. It may be made only of the stuff of consciousness, but ^ " Works," Vol. I, p. 259. F. J. E. WOODBRIDGE 161 then consciousness is the kind of stuff that may be condensed into a lump of sugar with which to sweeten coffee. Nor can we hope to obscure the fact by insisting that "states of consciousness'* are at best "representations " of other things, which other things have the quahties in question. For, however that may be, the "representations" have also the same qualities and obey the same laws. The world which we perceive turns out thus to be of the same general kind as the world in which the processes of perception occur. Even if the two worlds are numerically distinct, they are essentially alike. The problem of their relation to each other is not a problem of the relation between two natures radically different and heterogeneous. From these considerations certain conclusions appear to me to be obvious. If the processes of perception about which physiology and psychol- ogy inform us are the processes by means of which we perceive our world, then, if the perceived world is not continuous with those processes, it is none the less homogeneous with the world where they occur, and might contain them if they are ever given "in representation." If the processes belong to a world entirely physical, the "representations" belong to a world at least partly physical. In other words, if there is a physical world external to consciousness, there is also a physical world within consciousness. The physical things we perceive may not be the physical things which cause our perceptions, they 11 162 PERCEPTION AND EPISTEMOLOGY may be only representations or reduplications of them, but they are physical things none the less. There has never been discovered in "conscious- ness** any activity or power by virtue of which a physical thing even if reduplicated must lose its physical character or the general homogeneity of the world be disrupted. If, however, the proc- esses about which physiology and psychology in- form us are not the processes by which we perceive our world, the question of reduplication and rep- resentation is meaningless. We need no longer be perplexed over the problem of the homogeneity and continuity of the perceived world with the processes which give rise to it, for the problem then no longer exists. The conclusions stated in the preceding para- graph cannot, however, fail to modify our attitude towards the problem of such continuity. To sup- pose that physiology and psychology give us no reliable information is preposterous. Yet the fact remains that the perceived world cannot be located at any point in the perceptive process forming therewith a continuous series of events. Must we therefore conclude that there are two worlds, one representing the other, both essentially homogen- eous, and yet presenting a problem of continuity and relationship which we can never bring within the domain of positive knowledge, but of which we must always give only a speculative solution ? This conclusion has become less easy with the rec- F. J. E. WOODBRIDGE 163 ognition that the perceived world is essentially like the world of processes, is the kind of a world which might contain them and does contain them contin- uous with the rest of itself if the processes are ever given in representation. A world, a representative world, which can thus so faithfully copy, even in part, another world which is somehow its cause, would appear to contain within itself all the ele- ments necessary to show how process and result are related to each other, at least ''in representa- tion." And if "in representation," then surely the need of duplicated worlds has disappeared so far as any positive result for knowledge is con- cerned, for process and result would, in that event, be given in a manner wherein their relation to each other could be defined. It would appear artificial and strained, therefore, if we were to continue to suppose that the problem of the relation between process and result is ultimately of an epistemologi- cal character. It appears rather as a problem of reorganization and rearrangement, of new relations in one continuous world, not the problem of the reduplication of a world forever excluded from the place where it is known. In general, then, the problem of the continuity and homogeneity of the perceived world with the processes which give rise to it appears to be a prob- lem lying wholly within the domain of positive knowledge. We may proceed to solve it without first securing epistemological warrant for so doing. 164 PERCEPTION AND EPISTEMOLOGY If we fail, the reason can hardly be that we lack the proper epistemology from the vantage ground of which our procedure may be philosophically scrutinized and corrected. For, again, the proc- esses of perception are such as we discover them to be, or they are not. If they are not, there is no problem of continuity and homogeneity. If they are, that problem, from the nature of the case, does not involve the question of the validity of our knowl- edge of the processes or of the world resulting from them, but only the question of the sort of con- nection which exists between the processes and the resulting world. That connection is not cognitive, because the results of perception are not the knowledge of its processes ; the thing seen is not the knowledge of the mechanism of vision. The same result might be reached by consider- ing the problem of perception directly and in de- tail. There are many cases in which we make a distinction between what we perceive and what really exists, cases, that is, where we seem forced to distinguish between appearance and reality, and ask whether we perceive reality as it is. Every one is familiar with such cases. Who sees reality cor- rectly, the color-blind observer or the one not color-blind ? Now it is interesting to observe that when we attempt to answer such a question we really restate it so that it loses all its epistemo- logical character. For what we seek to discover is not whether the color-blind see reality as it is, but F. J. E. WOODBRIDGE 165 why they make the color discriminations they do. If we succeed in our discovery, we have learned that reality is so constituted that, given certain conditions, certain results are the outcome. We need no epistemology to estimate the truth of our discovery. Again: weperceive the stroke of the distant woodsman's axe and its sound in succes- sion. How, then, can we be said to perceive reality correctly, since stroke and sound are in reality simultaneous ? But the diflSculty thus presented is gratuitous. For most assuredly did we perceive stroke and sound simultaneously, the constitution of things would have to be different from what we have discovered it to be; light and sound would then travel at the same rate. The so-called spatial and temporal discrepancies in perception turn out on examination to be, not matters of cognitive im- portance putting the validity of perception in peril, but definite and ascertainable factors in the consti- tution of the world. The question, whether we perceive the world as it really is, turns out thus to be an ambiguous ques- tion. If it means, is a perceived world the same as an unperceived world, the answer is, naturally, in the negative. If it means, have we discovered how we perceive the world, our answer will disclose whether we have or not. But if it is claimed that from the nature of the case we can never tell whether the discovery has been made, it is quite idle to speculate about the matter. It would ap- 166 PERCEPTION AND EPISTEMOLOGY pear, therefore, that whatever problems a theory of perception may involve, they are not problems of epistemology, but of natural science and posi- tive knowledge. No matter what diflSculties these problems present, they furnish no warrant for the assumption that they necessitate an epistemol- ogy which shall estimate the truth of those bodies of knowledge we build up directly from consid- ering how we perceive and what we perceive. They necessitate only problems of definition and positive relationship. In the words of Jevons : " We can- not suppose, and there is no reason to suppose, that by the constitution of the mind we are obliged to think of things differently from the manner in which they are." ^ ^ "Lessons in Logic," p. 11. SUBSTITUTIONALISM SUBSTITUTIONALISM By C. a. Strong 1 O provide the metaphysical background neces- sary for a full comprehension of my theory, I must ask the reader to make with me a certain assump- tion. This is that our perceptive experiences are not in the order which they reveal, or rather not in the part or place of that order which they reveal, but in a place represented by that of the brain- events with which they are (as we say) correlated. The experiences, in other words, are the brain- events, considered in themselves ; and all other physical events, in themselves, are what may be called infra- experiences — something of like nature with human experiences, only far less highly or- ganized. This is in truth as reasonable an hypothesis as that the experiences are themselves in the physical (or rather the extra- bodily physi- cal) relations ; that is, it puts them in the same world with the object, only in a different place — in the brain, instead of in the object perceived. The chief advantage of the conception lies, to my mind, in permitting a better explanation of the relation of mind and body than would be pos- 169 170 SUBSTITUTIONALISM sible on the alternative theory. In any case I ask the reader to entertain it, and to note the con- sequences that follow in regard to the nature of cognition. By cognition, here, I mean mere apprehension of or acquaintance with an object, whether it be a physical fact or a mental state, a memory or a feeling in another mind — not that placing and classification of objects thus cognized which takes place by connecting them in thought with other objects similarly apprehended. The essential thesis of this paper is a proposition in regard to the mechanism of cognition as thus defined: that it happens by the projection of a sentient experience into the place of the object cognized, and is not a species of intuition (either in the sense of involving an immediate unity of cognition and object, or in the sense of appre- hension of the latter by a qualityless conscious- ness). By projection I mean that the experience evokes actions (and thoughts, which are a sort of actions) appropriate to the object and not to itself as an experience. Thus in memory (if I may assume that memory is the cognition of an earlier experience, and not simply the repetition in fainter form of a percep- tion) we have a past experience which is the object and a present experience which is the medium of knowledge, knower, or subject. The present ex- perience does not intuite the past experience (in C. A. STRONG 171 either of the above senses : either as identical with it — the past experience come to Hfe again — or as affording immediate and, so to speak, achro- matic vision of it). It is a more or less perfect re- production of it, and it provokes us to act as if what we had to do with were the object and not itself as a present state. In other words, it earns its title to be a memory by serving as a satisfac- tory substitute for the object in the regulation of conduct. We may call this the substitutional theory of knowledge, or, more briefly, substitutionalism. Substitutionalism must not be confused with what has been called the representative theory of knowledge. This theory supposes that what we have immediately to do with or cognize is the present revived experience, and that from this we pass to the object, the earlier experience, by in- ference. But, in the first place, there is no "we," distinct from the present experience, to cognize it, the notion of a qualityless consciousness being a superstition; but what we mean by "we," or the subject in this case, is precisely the present ex- perience. And, in the second place, this experi- ence does not in any way cognize or apprehend itself. What it cognizes or apprehends is the past experience or object, in that it reproduces it and will shortly elicit reactions appropriate to it. There being no other thing cognized in the premises, no middle fact or representative between subject and object, the cognizing must be allowed to be direct. 172 SUBSTITUTIONALISM So that, on our theory, the object is at once inde- pendently real and directly known. On the other hand it is not immediately {i. e.y without medium) but substitutionally known — known by the projection of a present experience, as truly possessed of definite qualities as the past experience it knows. The genuineness of the knowing will consequently depend on two things : (1) on the knowing experience reproducing the qualities of the experience known with sufficient accuracy; (2) on its eliciting reactions really appropriate to the latter. Now, since the function of cognition exists primarily and originally for practical ends, what is sufficient accuracy will be determined mainly by the eliciting of the right reactions ; whence it follows that, in a given case, the knowing experience may vary markedly from its prototype in richness of detail, in the cast of its qualities, and even in more fundamental ways, without forfeiting its pretension to be a memory so long as only it calls forth the right reactions. Hence we must distinguish that projection of the present experience which constitutes the past ex- perience as remembered from the past experience as it really was. The latter alone is the object of knowledge ; we shall be following accepted usage if we call the former its content. I need not say that this distinction is of capital importance — in no way inferior in importance to that so much insisted on between content and subject. C. A. STRONG 173 We are now in possession of the three funda- mental epistemological categories, which are SUBJECT, CONTENT, and OBJECT. I shall tr^' to establish that this account of cognition, with the distinction of these three categories, applies not only to memory, but also to perception, and even to internal observation or introspection. We are apt to suppose the case of perception essentially different from that of memory — to conceive that it involves actual experience of a present object whereas memor}^ only involves representation of an absent one. This is because we erroneously identify the object with the sen- sible appearance, or projected visual experience. A moment's thought exposes this fallacy. If the visual experience, either in itself or projectively, were identical with the object, the connected tactile experience, being something totally different, would be a second object; yet we feel that touch and vision have to do with the same thing. A blind man may as truly cognize a sphere by handhng it as a normal man by seeing it, may he not ? Then the sphere itself cannot be essentially either visual or tactile. But the demonstrative proof that the object is other than the sensible appearance is what may be called the lateness of perception. The sensible appearance is necessarily synchronous with the perceptive state; whereas the object (i.e., that 174 SUBSTITUTIONALISM phase of it which is perceived) belongs to an earher moment. Thus a star which we see in the sky may have ceased to exist ages ago: a sufficient proof, surely, that what we now see (I mean the visual phenomenon — not that which the visual phenomenon reveals) is not the object itself. We are habituated to the notion that a sound, for in- stance that of a distant whistle, is heard at a later moment than that at which its objective cause occurs — indeed, we see the escape of steam sev- eral instants before we hear the sound : we should apply the same analogy to vision. In both cases the perceptive experience arises only after the light-rays and sound-waves have reached the body. Hence the projected perceptive experience cannot be the object itself, but at most the object as per- ceived; it cannot be the object sensu stricto but only the content. Perhaps the reader may doubt whether there is any object distinct from the perceptive experience as projected; the assumption of one may seem to him to involve dualism and an outsoaring of ex- perience not permissible to an empiricist, or indeed to any other man. At least in the case of memory he will admit that we unhesitatingly outsoar both the present experience and its content, and assume an object independently real. But that object, you may reply, is only another experience. The answer suggests how the difficulty about dualism might be met in the case of perception: namely, C. A. STRONG 175 provided the object could be conceived as "only another experience " — as an outlying part of the world of sentiency, fundamentally of like nature with the sentient experience that knows it. In contemporary philosophical controversy we may distinguish the following three groups : the realists proper, maintaining that knowledge reveals an object independently existent; the transcen- dental idealists, holding that it discloses a content eternally valid ; and the immediate empiricists (or pragmatists in metaphysics), who teach that it has no reference beyond experience but is con- cerned with the evoking of beneficial reactions.* It may be interesting to note how these various contentions appear upon the substitutional theory. The case of memory surely bears out the con- tention of the realists, that the object has existence independently of the knowing state and is in no way constituted by its being known. And we have seen that the same thesis may be defended with reference to perception. It is only the object as remembered or perceived, the content, that is con- stituted by the knowing, and we may suspect that the transcendental idealists have mistaken this for the object itself. If, finally, the object in perception ' I omit the subiecti\'ists from this list because they play at present too effaced a role in philosopliical controversy. Subjectivism is the man of straw that every novice may spurn at, even though he have failed to assimilate the important insight it embodies. 176 SUBSTITUTIONALISM can be shown to be a non- human experience exist- ing at a moment shghtly earher than that at which we substitutional^ perceive it, the view of the immediate empiricists that there is no object inde- pendent of experience will only bear the construc- tion in which experience means all experience, not that in which it means the particular experience engaged in knowing. On the other hand we may concede to them that knowledge has no reference beyond experience in this sense, that there is noth- ing in the knowing experience itself at the moment to indicate that it is cognitive or self-transcendent, and that its being so comes to light empirically only in the subsequent fact that it elicits actions appro- priate to an object beyond it and not to itself. What the transcendental idealists call the object is, we saw, really the content. Now to the con- tent esse = percipi applies : it exists (or, more accu- rately, appears) only so long as the perceptive experience continues. So that regarding the fact of non-continuance the transcendental idealists — and the Berkeleians too, though what they refer to is perhaps rather the perceptive experience — are right, and wrong only in supposing what they are speaking of to be the object. On the other hand, if the substitutional theory be cor- rect, the naive realists are in error when they suppose that we perceive the object immediately (without medium) and as it is in itself. This con- ception shows that what they also, like the tran- C. A. STRONG 177 scendental idealists and the immediate empiricists, have in mind when they speak of the object is the sensible appearance or content.^ Now, if content and object agreed in every respect, both as to qualities and as to relations, knowledge would be as true, or, more exactly, as adequate, as if it were immediate; though even then it would not be so. But to take for granted that, despite their exis- tential distinctness, they do in fact thus agree is to overlook the large element of misrepresentation and mere symbolism that is consistent with the eliciting of the right reactions. Naive reahsm is indeed the essence of theoreticalism or what Kant called dogmatism. To sum up: the naive realists are the special champions of the object — but they exaggerate the directness and adequacy of our knowledge of it; the transcendental idealists are the protagonists of the content — but they mistake it for the object, and so are betrayed into declaring the latter a thing discontinuous and relative to the mind ; the immediate empiricists espouse the cause of (what they call) experience^ — but they overlook the fact that experiences are cognitive when they lead to certain reactions precisely because those reactions are adjusted to independent objects. ' Unless it be simply the perceptive experience. * What they call experience — for it will be found on examination that this is really content, or at least a fusion of content with experience in which the latter loses its purely sentient character and the former illegitimately gains existence. 12 178 SUBSTITUTIONALISM Let us next consider what these theories have to say about the knowledge of consciousness (or introspection so far as not apperceptive). The naive reahsts, since they mistake the sensi- ble appearance for the object and hold the latter to be physical and not in any sense psychical, must perforce assume a qualityless, "transparent" (I quote from one of them) consciousness as that which perceives it ; a consciousness whose existence is distinctly additional to that of the object. But since at the moment this consciousness is wholly engrossed with the cognition of the object and unaware of itself, and at the next moment it is gone, the assertion of it seems to rest upon no empirical basis — as the word " transparent" admits. Other naive realists seek to define consciousness as a peculiar kind of relation between objects, which objects can be in and yet get out of without for- feiting their existence: but, so far as the relation is additional to the things related, the preceding argument holds. Still others (now of the immedi- ate empiricist type) regard the object as in another aspect psychical, and tell us that the perception is "in the object"; but since the latter, as we have seen, belongs to an earlier moment than the brain- state which corresponds to it, this amounts to the paradox that the perception of a star, for instance, happened years ago and not at the moment when as a matter of fact we perceive it; or else to the supersubtle doctrine that perception is never per- C. A. STRONG 179 ception proper but always memory of a perception not ours. In short, the sensible appearance having been transferred to the place of the object, nothing verifiable remains on this side to figure as the perception of it. Emotions, pleasures and pains, desires, thoughts are obvious and discoverable states : perceptions are sought for in vain, or else relegated to the world beyond the mind. All this time psychology goes on assuming that colors and shapes in their immediacy are what we mean by perceptions. Evidently the excellence of the naive realist's knowledge of the object has cost him a subject. If, on the contrary, as the substitutionalist maintains, that which plays the role of subject or consciousness is an experience projected, and the projection is due to subsequent reactions making the experience virtually the object, that is, a cogni- tive substitute for it, then the moment we abandon the objectifying attitude involved in these reactions the experience (or a replica of it) stands before us in its immediacy as that which a moment ago was the subject or knower; knower not by force of anything intrinsic, but simply in virtue of its external relations and of the role which it played as a medium of adjustment to the object. The knower could never be known if it were not at the moment (I must not say experiencec?, but) experi- ence — an experience that can be recalled a moment after and then viewed in a different set of relations. 180 SUBSTITUTIONALISM The transcendental idealist, next, since he iden- tifies the object with the content and has nothing beside, and since content is a thing subjective in its material and objective in its reference, will declare object and subject to be aspects of a single fact. And this single fact he will doubtless (since he has nothing else) call by the name of "experi- ence." An experience thus, in the case of memory, means for the consistent trans cenden talis t not the past state remembered nor the present state that remembers it, but the past state as it appears to the present state ; in short, an appearance or phenome- non. And the trans cendentalist will stoutly protest that there is no subject to which "experience" is given (the subject, according to him, being merely the abstract / think which is another aspect of any content), the necessity of a knowing experience distinct from the content being thus confused with the necessity of a qualityless consciousness distinct from experience ; while his opponent, who agrees with him in defining experience as the unity of subject and object (i. e., in applying the term to the content), will as stoutly insist that, since con- tents are inactive things, they must be given to a subject or "activity" that is not empirical at all. From this maze of misconceptions and mutual misunderstandings the substitutionalist is saved by his insight that the proper thing to be called ex- perience is not an experience projected into the place of another experience but an experience simply. C. A. STRONG 181 But what is the proper thing to be called con- sciousness ? Consciousness, we have seen, may mean sentient experience so far as exercising tlie function of knowing, and this is the sense in which the word is commonly used by psychologists ; but it might also conceivably be used, and is indeed currently by philosophers, for the mere function of knowing considered apart from the existence that exercises it. This is the distinction between " con- sciousness as an existence " and " consciousness as a knowing." Content is the inner aspect of some- thing which in its outer aspect is a functional relation between two existences : the latter is con- sciousness as a knowing. There is indeed such a distinction of aspects, and consciousness as a knowing is a perfectly real thing (though it might better be called simply cognition) ; the error lies in denying that consciousness as a knowing is the function of an existence, or in conceiving that the existence of consciousness, in any sense in which psychologists have a right to speak of it, is simply the existence of consciousness as a knowing (which a httle reflection would show to be not an exist- ence at all). This distinction is, I think, the key to the inter- minable dispute over the efficacy of consciousness. Those who deny efficacy do so because they are thinking of consciousness as a knowing, or the ex- ternal aspect of content: which is indeed inactive, because not an existence. Those who assert it are 182 SUBSTITUTIONALISM thinking of consciousness as an existence, and sub- stitutionalism is proof that this may be con- ceived as of the nature of experience or psychical. But let us come to the immediate empiricists. Since they wholly reject an object distinct from the present experience, considering that the existence of experience is simply the givenness of objects, their cue must be to deny the existence of consciousness as a thing true at the moment and explain the con- ception of it as arising through the subsequent overhauling and rethinking of experience. They will therefore protest against the notion that expe- rience is inherently psychical. Experiences, they will tell us, are originally objective. They become subjective or psychical only when, viewing them in retrospect, we take them in a connection in which they did not originally present themselves. To suppose them originally psychical, to seek to build up the world out of experiences taken as psychical, is psychologism, a condemnable theory. Now, when the substitutionalist speaks of ex- periences as sentient or psychical, he does not of course mean that they are inherently cognitive or subjective. Experiences, we have seen, are cog- nitive only in virtue of an external relation. He means that they form the substance of the know- ing mind, and that perceptive experiences, for in- stance, exist in exactly the same way, and for the same brief space of time, as emotional experiences or experiences of pleasure and pain. Moreover, C. A. STRONG 183 though the recognition of the cognitive function of experiences can only be subsequent and retrospec- tive, yet what is recognized is something true of the earher moment: the experiences did actually stand in these external relations, and they were therefore originally cognitive or subjective although not in- herently so. The cognitive or subjective charac- ter is not conferred by the later retrospective act — experiences do not become subjective, as the immediate empiricist with a mistaken idealism suggests. But this means that they were, orig- inally, entitled to be called consciousness, in so far as the exercising of the cognitive function entitles anything to be called consciousness. The exist- ence of consciousness, in other words, should not be denied but its proper identity made clear. Strictly speaking, neither human experience qud exercising the function of knowing nor human experience qud sentient existence is entitled to be called consciousness. By its derivation — con-scious- ness — the word signifies the knowing of objects together with awareness of the subject. It refers to that common experience in which, when ab- sorbed in the contemplation of objects, we suddenly awake to the consciousness of ourselves as contem- plating them. Not the self or subject that con- templates, but self-awareness, is what consciousness properly means. It has, however, been trans- ferred by metonymy to the object of such aware- ness, the self or subject, and is constantly used in 184 SUBSTITUTIONALISM that sense by psychologists. Finally, philosophers have seized upon the word and applied it to the mere function of knowing, in so far as knowing appears to present its object with a contemplative directness. We may sum up these results by indicating their bearing upon the problem of metaphysics or on- tology — that of defining the ultimate nature of the world. The metaphysician who would base his theory truly on experience has occasion to ask himself with some scrupulousness what it is exactly that experience reveals : what it is that is given. For out of the fragments of the given, or others fundamentally Hke them — fragments material, psychical, objective, or whatever they may prove to be — he must put the universe together. Now "given" (that pet term of philosophers, which common men know not) is not only ambig- uous but triguous, if there were such a word: it may mean known; or present in the way of con- tent, conceived; or present as experience. (Present to what, do you ask, in the latter case ? Present as a schoolboy is present whose teacher has not yet arrived; present to the walls and the benches — here the infra- experiences that make up the rest of the psychic organism ; and the teacher, of course, the supervenient self- perception). (1) If "given" means known^ then what is known is exclusively the object. Whence it follows C. A. STRONG 185 that the universe must be put together out of ob- jects. And indeed, since philosophy may safely be said to be a synthesis of things which we know, there could manifestly be no better material out of which to put it together. But, in doing so, the philosopher must not allow any trace of experience or the knower to cling to the conception of objects — he must not say that objects are inconceivable apart from a subject, or that they are essentially some one's experiences — since otherwise he is including in the conception of what is known some- thing additional to what knowledge has revealed about it. It does not belong to the conception of a thing or existence to be known by or given to a subject; this is an extraneous relation, which accrues to it accidentally. It does not belong to the conception of my mind, for instance, to be known by you, though as an idealist you should egregiously think so. If then "given" means known, the universe consists of objects which are not essentially such, which are not experiences in the sense that they have anything of the knowing experience about their persons, and which are not other experiences than the knowing experience except so far as knowledge, original or subsequent, discovers this to be so. On the other hand these objects must not be taken at their face value, as identical in quality with what the first knowing experience presents them as being, since knowledge is substitutional and its primarily practical function 186 SUBSTITUTIONALISM allows of a considerable divergence between the first presentment of an object and the object as it is (and is finally discovered to be). What objects are we can of course learn only through present- ments, or through a collation and criticism of different presentments. This, we shall find, is the ultimate task of epistemology. (2) "Given," next, may mean present as con- tent (this indeed is probably the normal significa- tion of the word) ; and those who have nothing but content and who call that "experience" will accordingly hold that the world must be put to- gether out of experiences taken objectively. But an experience taken objectively means, in the case of memory, that you must not take the remember- ing experience and you must not take the experi- ence remembered, but you must take the latter as seen from the point of view of the former — in short, a memorial appearance. And, similarly, in the case of perception, it means that we must not take objects themselves, but we must take them as seen from a hundred or a thousand dif- ferent points of view. To perceptive and me- morial appearances we must add all the different conceptions of the real, the possible, the fantastic, the non-existent that ever have been — since every- thing that a human being has ever experienced is indefeasibly real, just as he experienced it — and put them together into a universe as best we can. The result will, I fear, be a universe consisting C. A. STRONG 187 in large part of men's foolish and erroneous notions of things.^ We shall later see that contents are not existences or metaphysical building- blocks at all, and that a universe composed of them is a mere chaos of appearances, a nulliverse. (3) "Given," finally, may mean existent as experience, and this is in one sense the givenest of all. That is, it is most direct and vital to the knower, to his inner life and sentiency. Unfor- tunately, in the other senses of the word it is not at all given, either to an intuiting "conscious- ness " or to itself or to anything else. What makes experience appear to be thus given is the fact that it is so easily emerged from and thought about. We thinking beings, particularly philosophers, no sooner have an experience than, presto ! we think about it and so convert it into an object. But in its primal character it was not an object; and so, if we take experiences in this sense and use them as building-stones to construct a universe, we shall again have to divest them carefully of all subjectivity and abjure the doctrine that the things which we know cannot exist without a knower. Now, since experiences, in order to be talked about by philosophers, must have undergone this sea- change and become objects, the third sense of "given" comes round in its metaphysical result to * But are not men's foolish and erroneous notions of things, it may be asked, parts of the universe ? Qud sentient experiences, doubtless, but not qud concepts. A concept is not an existence. 188 SUBSTITUTIONALISM the first sense, leaving those only who turn contents into existences insecurely perched between two stools. Objects, as we have seen, are given always sub- stitutionally, under the form of contents, and the knowing experience is, so to say, the uniform giver. While then it is false that the knowing experience is the only thing we know directly, since it is not known, or given in this sense, at the moment at all, it is the only thing that by projection serves for the presentation of objects and that can be known retrospectively in its unprojected immediacy. If, therefore, in retrospect we abandon the objectify- ing practical attitude that gave to it projection, we have before us the piece of reality which a mo- ment before we personally were; and this is the only piece of reality that can be given to us with so high a degree of immediateness and adequacy. This unique piece of reality proves, when so cog- nized, to be a sentient experience. But I shall be reminded that I have advanced the view that objects of introspection too are sub- stitutionally known, and asked whether this does not place all objects of knowledge, including even our most intimate experiences, in their proper reality effectually beyond us, so that what things are in themselves we can never know but only adjust our relations to them. We are now at the heart of the subject. This is indeed a searching C. A. STRONG 189 question, and if the suggested answer be correct panempiricism and all other gnostic theories must disappear from sight in the Unknowable. The question has two stages : (1) What ground have we, rational or other, for assuming that the knowing experience has to do with an object at all, distinct from its content? (2) What ground have we for thinking that tPie content holds good of or describes the object, so as really to give us acquaintance with it, or is true of it in any other sense than that of enabling us to live in its presence? These are questions too large to be discussed in the present paper. I will only say that to me per- sonally it does not seem impossible to answer them satisfactorily, and to obtain the iBnal ac- quittal of knowledge (ultimate knowledge, that is) from the charge of not telling us the truth about reality. Let us consider, in closing, certain consequences of the fact (if it be a fact) that the knowledge of consciousness or human experience is substitu- tional. We should have here the same trio of cate- gories — object, subject, content — as before, and, introspective knowledge being retrospective, the cognitive relation would again be aimed backward, as in memory; there would be, in other words, the experience introspected, the later experience medi- ating introspection of it, and the projection of the latter into the seat of the former in the shape of 190 SUBSTITUTIONALISM content. Hence the possibility of the same three theories as before: a reahstic theory ignoring the whole apparatus of cognition and supposing the introspected experience somehow to stand before us with aboriginal immediacy and authenticity — naive realism, in short, in the field of introspection ; a transcendental ideahsm in the same field, regard- ing the mental fact as a thing whose essence con- sists in being observed (the proposition "feehngs exist by being felt" being confused with the propo- sition "feehngs exist by being introspected") and degrading our states of mind to the level of appear- ances and patches upon reality — in one word, epiphenomena ; finally, an immediate empiricism denying the psychical, as we have seen, to be a proper character of experience or reality at all. The labor of the substitutionalist must be devoted to showing, if possible, that in this case too the de- liverances of knowledge strike through to reality and illumine it. But we have once more been brought round to what is the deepest problem of the theory of knowledge — a problem of validity and not of mere mechanism: whether it is possible to make good our instinctive conviction that knowledge is really knowledge. In the foregoing essay I have talked bravely of "my theory," but the instructed reader will have recognized that it is in essentials Professor James's, C. A. STRONG 191 as may be seen from his articles " On the Function of Cognition," Mind, 1885, pp. 27-44; "The Knowing of Things Together," Psychological Re- view, 1895, pp. 106-111; and "A World of Pure Experience, I," Journal of Philosophy, etc., 1904, pp. 538-543. Honor then to whom honor is due. WORLD-PICTURES WORLD -PICTURES By Walter Boughton Pitkin It once happened that a circle of logicians and scientists withdrew from the turmoil of daily life to discuss the important questions of metaphysics. After having talked and waxed wise through learned intercourse for an unknown period, one of them chanced to look off into the world they had tem- porarily deserted, and discovered, to the dismay of the whole party, that the common people had fallen under the sway of a band of base sorcerers during their absence. The sorcerers, it appeared to the horrified onlookers, had won the masses over to a cheap but pleasing philosophy by play- ing upon their artistic instincts. From the shouts that reached the ears of the thoughtful men, it was inferred that the entire world of ordinary con- sciousnesses had gone mad over a picture philos- ophy, for men were heard to say: "I have a very good picture of that in my mind," and "The scene is indelibly printed upon my brain,'* and so on. And hordes of the possessed gathered around the sorcerers to listen with bated breath to Platonesque discourses. Filled with pity at the plight of the multitudes thus enthralled by miserable magic, the 195 196 WORLD-PICTURES thoughtful men resolved to descend forthwith from the windy hilltop where they had been convened and to break the insidious power. After seeking vainly to disillusion some common people encountered on the downward road, the thoughtful reformers united in an onslaught upon one of the sorcerers whom they overtook just as he was about to wave his wand of sophistries over a large band of young men who had come to him in search of the Truth. The reformers held their peace long enough to hear the first words addressed to the newcomers. But no sooner had the sorcerer proclaimed that his was a philosophy of world- pictures, than a biologist in the ranks of the thoughtful men cried out: "Spare yourselves the temptation of being lulled by these phantasms, O youths ! There are no world- pictures.'* " A madman ! " somebody hooted. But the biolo- gist was undaunted. " Call me what you will. The truth stands that there are no world- pictures. We men of science and philosophy have wrestled over the problem a month for every minute your misguided teacher has spent seriously over it; and in spite of many dif- ferences on other matters we agree that the world is so constituted that pictures are impossible. What you imagine are pictures are only rough symbols, signal lanterns in the night of ignorance." "He speaks in pictures himseK!" exclaimed a fair-haired artist. WALTER BOUGHTON PITKIN 197 "If you do not want us to smell a joke," called out a serious young engineer in the throng, "give us reasons for the faith that is in you." " Look at that great dog across the road, young sceptic," the biologist said, "and tell me what you actually see." "A shaggy, good-natured, young St. Bernard." "I have blurred the paint on your world-picture sadly!" retorted the scientist tauntingly. "You see only a colored form, various shades of red and yellow, all of which you interpret by a sheer act of your own mind as a shaggy, good-natured young St. Bernard. You do not see the name, nor the size nor the shape nor even the color you ascribe to the dog. I should like to know what sort of a picture the world has given you of itself, then." "The man's right!" exclaimed the artist in ad- miration. "I can speak with all the authority of my painful experiences in my master's studio; the colors and forms you think you see you just im- agine. But, after all, I'm not sure that this dis- proves all world-pictures." "It doesn't," joined in a chemist. "World- pictures are not these common hasty perceptions that rush in and out of the mind like flares of sum- mer lightning. The great teacher " — pointing toward the sorcerer, who was listening courteously but with some trace of amusement — " means by world- pictures the scientific theories that have been 198 WORLD-PICTURES built up by painstaking experiments and strict logic. In our mental picture of the law of gravitation, for instance, we have a genuine photograph of the be- havior of masses. All the refinements of trained observation and reflection have contributed to make this law an exact statement of the facts about which it speaks." "True, save for one word," the biologist an- swered. "Your law formulates the nature of gravi- tating matter with a few letters and mathematical symbols; but it does not truly picture it. It is a shorthand expression for the behavior of an infi- nite number of molecules, meteors, and nebulae. But it does not give you an actual image of all the motions of telescopic and microscopic bodies to which its brief signs refer and of which they claim to be an explanation. And you should be glad, young men, that you do not have to know the laws of Nature through the medium of pictures. If your minds were photograph galleries of the uni- verse, you would soon be as embarrassed as a shopkeeper who tried to keep account of all transactions in his store by setting up a kinetoscope wherewith to snapshot the acts of clerks, cus- tomers, and wagon boys. Your knowledge of the world is luckily a set of accounts with Reality ; your theories are the abbreviations of a bookkeeper, and they have all the advantages of brevity, simplicity, and freedom from useless details. Why crave so madly, then, for world-pictures, when you WALTER BOUGHTON PITKIN 199 already have something infinitely better for human purposes?'* Silence reigned among the hearers. Finally a country doctor agreed that the scientist's words fitted admirably in with what was known about the mechanism of the nervous system. "I never could straighten out the puzzle of world- pictures," he confessed. "How physical objects can ever reproduce themselves at the inside ends of the sensory nerves is simply unimaginable. I can understand how some sort of a current passes along the nerve tracts and registers itself somehow in the form of consciousness." "Wonderful man!" was the murmur of many. "This is the arch -mystery." "But it is absurd to say that the effect of a long chain of intricate causes can look Uke some early member of that chain." "Perhaps the dissenter is right," a waverer shouted. " Let us turn him upon the great teacher himself, and we shall at least listen to a rare debate." "Pray do not call me a great teacher," expostu- lated the sorcerer, as the crowd pushed the biologist and his thoughtful friends up to the steps from which the talk on world- pictures was to have been held. "I am only a poor artist who could never make a living with brushes and paints, on account of my bad habit of indulging in metaphysical dreams about the nature of pictures when I should 200 WORLD-PICTURES have been grinding out charcoal studies. While philosophers and psychologists have been busily delving into the mysteries of neurons and percep- tions, I have contented myself with an innocently unphilosophical study. But, would you believe it ? after having Ustened to many wise debates about the nature of knowledge, I became convinced that, in order to speculate about the relation of mind to the real world of which it is a part, one must know more about pictures than about the cortex. For in order to discuss rationally whether experience is pictorial or representative in any manner, we must first make perfectly clear in our minds what we understand by a picture. Or, as a mathema- tician might put it, we must make certain postu- lates about pictures ; these postulates being derived in conference from our habitual, rough use of the word * picture ' ; and then we must see whether ex- perience, when critically viewed, can sustain these postulates. But which of the philosophers has ever done this.^" "We have been hearing about world- pictures and all other kinds of illustrated editions of the cosmos ever since the days of Plato," broke in an eminent physicist among the reformers. "So, if you can tell us anything new about these things, I shall go to church in the art galleries. Though I have never bothered to consult the dictionary about the word, I am sure a picture is simply * anything which, when perceived, suggests to the WALTER BOUGHTON PITKIN 201 spectator some other object by virtue of its own resemblance to the latter.' ** "An excellent beginning," said the sorcerer. "You distinguish it from a symbol by the fact that the picture itself looks like the portrayed thing, while the symbol need not. But let us look farther.'* And the crowd drew closer to the speakers. " How complete must the resemblance be in order that we may fairly call a thing a picture?" "Why, any perceived resemblance is enough to make the object resembling another a picture of the latter. The rude Hues of a newspaper carica- ture constitute a true picture. And yet, the line between symbol and picture is not a sharp one ; a representation of a very inquisitive person which showed the subject in the form of an interrogation mark on legs would be a picture only in so far as the clothing, facial expression, or some other one feature were actually portrayed." "Of course, you know that a fixed portraiture in colors or stone can give only one aspect of its subject." "No artist can show in a single landscape how a country-side looks from twenty different hilltops." "As there are indefinitely many aspects of physi- cal objects, it follows that there are as many sepa- rate pictures possible, does it not?" "And even more. In painting, at least, the view 202 WORLD-PICTURES from each angle and distance varies widely accord- ing to the color and intensity of the illumination and the clearness of the atmosphere." "When Thackeray drew a picture of a huge cloud of powder smoke and labelled it *The Battle of Trafalgar,' was this drawing called a picture of the battle only by way of witticism?" "From the philosopher's standpoint," laughed the physicist, "a cloud of smoke was doubtless a real aspect of the famous sea fight. So, too, might a sohd blackish smear on a canvas be a * life-like' picture of a colored gentleman in an unlighted cellar on a rainy night. All this, my dear sir, is true but not philosophy." "Perhaps not; but bear with me a moment. It often happens, I believe, that a single splash of color can, under certain conditions, be a perfect picture of a man's face, or of a house, or of a tree, or of almost anything visible." "Certainly." "You have observed," the sorcerer went on, " that the conditions under which you see a picture best are not those under which the portrayed thing itself can be best seen. An artist may look at a seashore on a gray, misty day from a vantage point a thousand feet from the strand ; but the spectator of his picture will not stand a thousand feet away from the canvas nor put the picture in a gloomy corner in order to get the intended effect." "Surely not!" WALTER BOUGHTON PITKIN 203 "It is hardly necessary to remark that the ma- terials entering into the composition of a picture need not be the same as those of the portrayed object." Merriment stirred the assemblage. "As if a portrait of Washington had to be made of human skin, eyes, hair, and clothes ! " was the cry. "Why, the masters of music even picture emotions with nothing save melodies and chords." "Do you not see," said the sorcerer, "why I believe in world- pictures ? The resemblance be- tween the empirical phase of an object at a given moment and the total nature of that object need be no more than the peculiarly limited resemblance we find between a portrait and the person depicted. What the *mind stuff' is, out of which empirical phases of things are made, I 'm sure I cannot say ; and for our present purposes, this problem need not be solved. It is enough to know that, as a matter of every- day fact, these empirical phases do suggest, stand for, and imply other things than their own bare selves. And, even if we were to admit that these suggested things are in turn noth- ing but revivals of previous experiences, we should still properly call the former true pictures. Again, though we might concede, as some psychologists do, that there is no evidence to prove that one experienced character revives an old one by virtue of their qualitative resemblances, we should still have a right to say that the former is a picture of 204 WORLD-PICTURES the latter because of such resemblances as may be experienced after revival. "But there is a real world which is known only at intervals and partially, as every dictate of prac- tical thought compels me to believe; and experi- ence asserts itself to be some sort of a picture of that world, though in what precise sense men are not agreed." A psychologist who had been listening to this dia- logue with growing vexation burst out at this point : "You are playing with us, O sorcerer. You talk of art works and would have us spring on the nimble wings of analogy to mental pictures. But if you seriously mean to defend the theory that your experiences are pictures of things outside of experience, I beg you to show me how you can possibly be aware of this startling fact. In order to know that a thing is a picture of something else, you must be able to put the two side by side for a comparison. How can you compare an experience, though, with something beyond all experience? How, with only a conjectural picture of an unseen, unknown object, can you pronounce the likeness good or bad?'* " This is the crucial question. The comparison of appearance with reality cannot be made directly, of course. But it is forced upon us all by our inevitable conception of the relation between cause and effect. Is it not agreed that the effect of a given cause is both like and unlike the latter ? Like WALTER BOUGHTON PITKIN 205 the existence of the causal relation itself, this is unprovable in strict logic; so you may call it a * category ' or a ' postulate,' as you please. But the fact remains that it satisfies the essential de- mands of a picture theory; for, in so far as we have to think of every effect as being like its cause in some aspects, we have to concede, I believe, that every effect bears the same relation to its cause in reflective experience as a painting does to its theme in perception. For all our experiences are both causes and effects ; thus it comes about that so far as they are the latter, they are ' expressions * or * manifestations * of a wider reality. Incidentally, too, I might say that, in so far as they are causes, the real world is an * expression ' of human nature. It is not fair to protest against such world- pictures on the ground that the resemblance between cause and effect may be a mere mental necessity, a bare postulate, or something even more human. For, as in any ordinary work of art, it is just this mental necessity of experiencing one thing to resemble another that establishes the pictorial relation." Said an eminent physicist who had thus far held his peace: "These abstruse words don't convince me that experiences are not mere symbols ; never- theless, I am charitably inclined towards your pic- ture theory ; for I believe that it could not bind a spell so easily upon all these thousands of business men and common people by empty tricks and wand-waving alone. Furthermore, I have observed 206 WORLD-PICTURES a peculiarity of organic matter which leads me to suspect that world- pictures are not utterly absurd. Let those who scout pictures on logical grounds alone consider that living forms have the power of impressing upon ordinary matter their own structures and functions. The segmentation of the lowest bacteria illustrates this as well as does the growth of the highest vertebrate. Is this not evidence enough to make us cautious about denying that matter can reproduce its own form and function in a different manner, namely in the world of experience ? Merely because we cannot describe how this happens is no reason for doubting the event, any more than our great ignorance of the details of organic self- propagation should be an argument against the reality of birth and inheri- tance. Reason with me, therefore, as with one whom you may perhaps convert." The thoughtful men smiled among themselves at these words ; for they well knew the potent ar- guments the physicist held in readiness for the sorcerer's attack. "As I understand you," the teacher said, "you say these signs do not portray the nature of the great environing world, but simply serve to tell us how to* act in reference to it." " That 's it. I do not deny, as some of my friends do, the existence of an external world. I see that it is illogical to infer from the fact that everything about which we can talk and think is ipso facto an WALTER BOUGHTON PITKIN 207 experience, the conclusion that these things are nothing but experiences. The dog I see over yon- der may, so far as logic goes, be at one and the same time a percept and something more, say a living animal. So you see, I stand half way be- twixt my friends who say the whole world is noth- ing but a complex of experiences and yourself with your theory of world- pictures. I differ from you in that I cannot see how anybody can know our experiences to be replicas of something outside of us. I think we have been led into the error of calling them such by virtue of their efficacy in prac- tical life. My idea of that dog, for instance, I call true because its claims can be substantiated by later experiences. I do not ever compar'e my per- cept with a transcendent canine and find it to look like the latter ; the seen, heard, felt, and smelt ani- mal simply behaves consistently with the action and character demanded of him by my thought of him.'* "Suppose we try your theory on the dog," the sorcerer said. " Tell me once more what you now experience the dog as.'* "A St. Bernard, perhaps three years old, a jovial beast apparently, and with an exceptionally long, curly coat of brown and yellowish white. I might add more, but this will do." "And how do you prove all this?" " I ask his owner about his age, or even examine the animal's teeth and claws. I feel of his hair to test its length and texture ; and I compare its color 208 WORLD-PICTURES with some standard shade. You see, I merely com- pare later experiences with an earlier one that is undergoing a test in their crucible." "And do you believe that, while you were per- ceiving and testing the St. Bernard, the real object causing or contributing to cause your perceptions of the dog was substantially the same throughout the whole test? Or might a wholly new object have shot into your field of vision and touch and hearing every millionth of a second without varying either your perception or what you were referring to in your thoughts?" "Of course, I can never prove this does not happen, for all my proofs are based, in the last analysis, upon differences in objects which can be perceived by some device. But the general lawful character of the world and especially my ability to manage it successfully with the aid of my ideas about it proves, for all practical purposes, the non- existence of the cosmic jest you have described. The same dog that I first saw is the object of all my later thoughts, and also the objective source of the perceptions I use in testing my original opinion of the beast." "Excellent! I see you are willing to accept a common-sense assumption. Now tell me whether the objective dog proved by his actions, i. e., by the kind of perceptions he led you irresistibly to in your test, — that he is really what you thought him to be at first?" WALTER BOUGHTON PITKIN 209 "Certainly the objective animal is the kind that produces in me experiences of a certain kind,'* the physicist admitted. " But, bless you ! this is a very different story from the one you have been singing about world- pictures ! Don't you see the vast dissimilarity between knowing that a percept is really of an external object that produces certain other percepts, and knowing that a percept is a copy of an external thing ? I am saying merely that my first perception of the St. Bernard was true because, when accepted at face value and acted upon, it led up to other perceptions which it originally implied. Each perception is a symbol or mental sign of a reality ; I cannot see therefore how a system of connected symbols can, simply by virtue of their power to hang together and cor- roborate one another, become replicas of the object to which they refer. You might as well say that a bookkeeper's balance sheet, whenever it * comes out right,' is therewith transformed into a dupHcate of the events and merchandise to which its figures refer !" "Your ignorance of pictures has led you into two bad arguments. Although you have admitted that the objective entity we call a St. Bernard dog produces your perceptions (in part, at least), you refuse to call these perceptions pictures, even when they express the behavior of the external real. The real dog, you say confidently, is the object from which certain colors, forms, motions and other 14 210 WORLD-PICTURES qualities come into your mind; furthermore, he gives you somehow a knowledge of the way he acts in response to various stimuli, for you can make him do certain things, by whistling to him, commanding him to * charge,' beating him, and so on. And yet all this knowledge, exact enough to guide even your future conduct, is not an expression of a real aspect of the external animal. Strange forgetfulness ! You do not admit the possibility of there being a class of world- pictures like that well-known vari- ety of human pictures which we call dramatic expression." " O wild dreamer ! Do you want us to believe that the universe is both playwright and come- dian.'*'* a metaphysician bawled. "Not at all. I should be glad, though, if you would agree with me that the performances of comedians are only peculiar developments of a common property of all experienced things. And this is no mysticism nor cheap anthropomorphism. Dramatic expression is simply expression of actions. I would ask you to believe nothing more than that the image of a thing's behavior in one or more situa- tions is a genuine 'picture of the thing. Always an aspect though, you should remember. As the tragedian expresses the true nature of his char- acter by his behavior, his gestures, and his mien, so do these thrills in our organisms we call colors, sounds, and so on, express the natures of their objective determinants. Does not everybody as- WALTER BOUGHTON PITKIN 211 sume this in practical life ? The engineer finds the nature of his steel girders 'expressed' in their re- sistance to stresses, strains, acids, heat, cold and so on. Things are truly what they do, in popular and scientific opinion. But does this not mean that they are reflected, in some manner, in their effects ? And does this not make invalid your analogy be- tween percepts and a bookkeeper's accounts ? Mental signs are the effects of the very things to which they can be made to refer, whereas arithmet- ical characters and devices of entry in bookkeeping are inventions of a person who is only in the slight- est degree conceivable, an effect of the merchandise whose movements he records with his symbols." "Another point," the sorcerer continued. ''Hav- ing overlooked the peculiar virtues of 'moving pictures,' you add confusion to your error by talk- ing about » pictures as 'replicas' or 'duplicates.' And by showing the absurdity of ' mental reduplica- tion,' you fancy you have shattered the ordinary man's faith in world-pictures. You convince me more firmly than ever that philosophers should give more attention to pictures. It was not I nor my fellow- believers who started this rumor about mental pictures being replicas of external things. We mean by pictures just what every ordinary man and every artist does ; something that presents an aspect of another; or, to avoid philosophical disputes, a presented aspect of a thing. I have never seen a picture in any gallery that pre- 212 WORLD-PICTURES tended to be a replica of the thing it portrayed. One picture may be a repHca of another ; but this means that it presents the same aspect of the por- trayed thing as the other picture does. Some wicked sophist has confused most inartistically du- phcates, models, and pictures. And he has thereby done violence to the English language and, still more disastrously, perturbed the ponderings of philosophers far and near. A duplicate, as any dictionary will tell you, is an exact counterpart of its original ; we may speak of an inaccurate copy, but never of an inaccurate duplicate. In daily speech, we might call one coin the duplicate of another of the same minting; but when talking philosophy, we must deny that any two material objects can possibly be true duplicates. There are always some differences, if not in molecular structure then surely in the stresses and strains due to different spatial position with relation to other objects. Taking this strict interpretation, who could be so foolish as to suppose that the things in mind are duplicates of any external originals ? Remember, furthermore, that a duplicate is not a copy merely in appearancey but also ' in substance and in effect,* as the dictionary says. Thus, a document looking precisely like the Declaration of Independence is a copy or facsimile of that document ; but it is not a duplicate, because it is not a statement of rights and intentions of a body of men identical with the signers of the Declaration of Independence; it WALTER BOUGHTON PITKIN 213 does not disturb the equanimity of our English cousins, it has not the history nor the sentimental value of the immortal brief. Look to the law, my friends, for light. You will find this distinction between copy and duplicate is sharp and worth preserving in our discussions. Speak of mental pictures as duplicates, and the absurdity of the name appears at once in nearly every case. My thought of a cow is not identical with the cow thought of *in substance and effect.' "Nor," continued the sorcerer, "can we speak of world models. For a model means an object, usually in miniature, representing accurately the structure, rather than the outward appearance, of its original. A model can, to be sure, look like its original in many respects ; but this is not always necessary ; neither need a model function precisely like its original ; the formal arrangement and con- nection of parts is the essential feature. I speak now, you understand, of models in the sense used by engineers and draughtsmen. You will surely agree with me that our experiences are not mechan- ical models at all ; for the blue I see in the sky is not a pattern of the molecular arrangement of the air and the nerves involved in giving me that blue sensation. If it is impossible to call our experi- ences models of external things, there is a little danger in describing them as plans; I hesitate to use this term generally. It is confusing. A plan, being something which shows the parts of an object 214 WORLD-PICTURES in their proportions and relations, does not give the appearance of the planned object, but only a certain indirect indication of its structure, as the latter is known to be through a large series of measurements, taken at various times in different ways. A plan, we might say safely, gives the ap- pearance of an object only to a person who knows the rules of the draughtsman and the general char- acter of the thing he patterns. In experience. Na- ture is somehow her own draughtsman; but she does not follow a cut- and- dried rule of draughting, as the architects and engineers do in their work. The latter occasionally make perspective plans as well as projective ones ; but they never go far be- yond these two types ; experiences, however, re- veal not only the geometrical relations and structure of external objects but their motions, effects, inter- actions, and a thousand and one other peculiarities. For this reason, the word *plan' strikes me as much too narrow; aside from this, too, there is the well-known ambiguity of the word, which sometimes misleads thinkers into the fancy that experience reveals a *plan ' — i. e., a design or pur- pose — of the universe. Whether there is such a design or not, I do not know; but I am sure that no mere analysis of the nature of experience will reveal one." "But!" exclaimed a philosopher in the rear of the crowd, "you surely recognize at least personal designs in all ideas and theories ? " WALTER BOUGHTON PITKIN 215 "Of course our wishes decide what goes into some of our world-pictures. And we plan later pictures so as to harmonize as well as possible with earlier ones. But this proves nothing about cosmic aspirations." "Perhaps not," a logician interrupted. "But it does demonstrate the nonsense of world-pictures. The scientists' plan of molecular structures is no more a true picture of matter than a hungry man's craving for meat is a photograph of a sirloin. Out of your own mouth you have made your pictures simply convenient plans of action, tools of thought which serve only to help you get along in life. Fre- quently you change your mind, get weary of old theories, and make new ones; sometimes because new discoveries force your hand, again for sheer love of mental gymnastics. Are these creations, in which personal impulses are mixed thickly, representa- tions of anything save your own sweet will .?" " Surely ! You speak as though my purposes were somehow painted in my world- pictures. As though the purpose of an artist who painted a moun- tain from the southeast at a distance of one mile from its base during early April mornings neces- sarily made all resemblance between canvas and mountain impossible ! Do you not see that, out of thousands and even millions of aspects of a given object, the man with a purpose simply selects those that suit him ? And, unless he is deliberately trying to play with the object, as a poet playing with horses 216 WORLD-PICTURES and men in fancy evolves a centaur, he does not wantonly add to the scene any marring evidence of his purpose. But let us suppose his selection of aspects is very unusual ; does his curious purpose prevent men from grasping his picture as a genuine representation ? "Consider your own attitude toward any ordi- nary picture ; when you stand before a landscape by Corot, do you fail to base your appreciation of the curious lights and the charming vagueness of even the grosser details upon your real or as- sumed knowledge of the artist's purpose? Do you say : * This is no picture at all, because Corot has omitted thousands of minor lights and shad- ows and has heightened, out of his imagination, certain dominant tones in the scene, which a spec- tral analysis of the lights he actually saw in the por- trayed landscape would never reveal ? ' No, you judge his work from his own standpoint, as nearly as you can. You put yourself in the place of a man whose purpose is to bring out certain airy, romantic aspects of ordinary sunlight which men usually feel but cannot abstract from other pecul- iarities, such as sheer brilliancy and color ; the place of a man who is trying to show masses of light rather than the details of things that are in the light. And you say, if you have any appreciation for this standpoint, that the picture is a wonderfully * true * reproduction of the real landscape. "So too with the physicist's picture of molecules. WALTER BOUGHTON PITKIN 217 It is a plan of action, to be sure ; but only because it is supposed to portray the nature of the matter the scientist deals with from the particular stand- point he wishes to take. Wishing to describe the behavior of material objects in mathematical terms, he looks at his data so as to bring the de- sired aspects into the foreground. But look how some turn this fact. They say that, because the scientist thinks out molecules from the point of view of their use in interpreting certain phenomena, therefore these entities and their determinations, however definitely conceived, should not be held for literally real. It is as if they existed; but in reality they are only artificial short-cuts for taking us from one part to another of experience's flux. They are only 'extraordinarily successful hypoth- eses.' If these men had only studied the rudiments of art, how easily they might have avoided this fal- lacy ! They have failed wholly to see that, bound up inextricably with the very function and nature of a picture, is the selection of a standpoint; and with a standpoint goes an angle and an 'atmos- phere ' and, at least in the case of humanly devised pictures, among which it is fair to reckon our idea of molecules, the 'medium of expression' — the paints, brushes, and canvas, or again the words, signs, and formulas. They do not see the useless- ness of refuting the picture theory of knowledge by trying to load impossible and unheard-of responsibilities on our poor pictures." 218 WORLD-PICTURES "Is matter really composed of molecules and atoms or not? " an untutored mind inquired timidly of the sorcerer. "It is really molecular and atomic, just as the sky you see overhead is really blue. For what do you mean in each case ? When you say the sky is blue do you signify that a man in a balloon ten miles up in the air might find tiny particles of mat- ter which, under a sufiiciently strong microscope, would appear blue precisely as the sky does as a whole to you from your present vantage point .'^'^ "No. I mean that the sky is really of such a nature that its appearance from certain positions and under certain conditions of light is blue.'* " In short, the real nature of the sky is not some- thing we can talk intelligently about *in general,* but must always be considered and judged from a specific standpoint and under specific conditions ?** "I should say so. I cannot imagine what a shy in general would be.'* "Why!" exclaimed another untutored mind, with much disappointment, "then molecules are only appearances, after all ! Matter simply looks like a molecular order from the physicist's stand- point at present. A nearer view under better conditions of observation may prove this hypoth- esis false. And then everybody will agree that all chemistry has rested upon a mere appearance for generations ! Verily, we are such stuff as dreams are made of!'* WALTER BOUGHTON PITKIN 219 "Cheer up!" cried the sorcerer merrily. "You are eating bread and pretending it is a stone. You are letting the metaphysicians confuse you with their vicious identification of 'mere appearances' and real aspects. Of course, the material world presents itself from certain angles and under cer- tain conditions as being composed of molecules, atoms, corpuscles, and may be something even finer. Of course, men's notions about these con- stituent parts are constantly changing with the growth of knowledge. But so is the view of a moun- tain as you slowly approach the earth monster from a distance. If you say in ordinary common-sense life that each view of the mountain gave you a real aspect of it, not a mere conjecture or illusion about it, why not be equally unsophisticated when talking about views gained reflectively ? By what right do you refuse to call a picture taken at a distance with a poor lens less truly a picture than one taken at short range with a finer camera.'^" A biologist spoke for the untutored mind. "I refuse to call an error a representation of the thing it erroneously refers to. The blue sensed by the ordinary man when he looks up at the sky is construed by him as a picture of the upper atmos- phere and nothing else. Yet we know the color is really a curious mental expression of a vastly complex interaction of air, ether, and nerves. As well call a picture of me one of you because you happened to be a party in its making!" 220 WORLD-PICTURES "Would you say," the sorcerer retorted impa- tiently, "that a canvas whose figures, coloring, and general purport you could not interpret at first glance was not truly a picture of anything ? Or would you pronounce a photograph of some scene a pure illusion if you had mistaken it for a repre- sentation of some other scene ? It seems to me that no specific error, however gross, supplies us with the slightest evidence against the picture theory; indeed, I am not sure but that the very attempt to base an epistemological doctrine of either subjectivism or symbolism upon the char- acter of perceptual error must subtly assume some pictorial function in experience. For one percep- tion or thought can claim superiority over another only by proving through practical tests that its own specific nature more adequately expresses the nature of the situation of which it claims to be an aspect." "But how about cases of complete error?" asked a psychologist impatiently. "Do you say that the seen blue is whatever it comes to mean ? " " I think I am forced to this ; but do not miscon- strue the facts !" " Good ! Then a neurotic cloth merchant might interpret the blue as a huge silken canvas stretched over his diseased universe. A color-blind barba- rian, unable to distinguish it from yellow, might call it a cloud of gold dust in the heavens. A child might think it a sea of water. And so on WALTER BOUGHTON PITKIN 221 through a thousand vagaries. Now, do you really mean to say that this one identical blue is at one and the same time a true aspect of a cosmic sheet of silk, an aureal mist, a suspended ocean, and all the other fancied objects to which it is at- tached by raw or sickly minds?" *' Exactly ! Under the special conditions of each case, the simple color whose character may be proved by proper experiment to be given by the illumined atmosphere acts so as to mean or look like some curious thing. But the factors deter- mining the interpretation or * acquired meaning' of blue from moment to moment are obviously not identical with the factors bringing into existence the simple blue itself, any more than the causes of a photograph are identical with the causes of a man's thoughts about the latter. So, you see, I am quite prepared to admit that things are pic- tured which exist as pictured only under unusual cerebral conditions." "But," said the physicist, "you have pointed out such a radical difference between ordinary pictures and cognitive experiences that I for one object to your calhng the latter world- pictures. You say the blue I sense is, in some measure, an effect of the sky to which I come to refer it ; so too is the act of interpreting the color one effect of the color itself. You thus make the experience, in all its stages of development, a phase of a real, more than empirical thing or complex. It is not a 222 WORLD-PICTURES copy, it is an aspect of the thing itself. Is it not doing violence to language to call a part of an ob- ject a picture of the object? I am willing to con- cede that experiences may not be bald symbols, for you have convinced me that they are closely related in nature and behavior to the whole order of things to which they refer and through which they guide us ; yet I cannot call them pictures. I am willing to compromise, however, by calHng them aspects." To this the sorcerer replied : ** I was long in doubt over this same question of terminology. It is true that men ordinarily think of a picture as a wholly external, independent representation. But is this not merely a practical abstraction ? As a scientist and philosopher, would you not admit that even the most imaginative painting or trick photograph is an aspect of what it portrays, just in so far as the latter has influenced the artist to copy it or the spectator of the picture to interpret it.?'* "You mean,'* inquired somebody, "that, philo- sophically speaking, even a word picture, say a description of a battle, is truly a phase of the battle, just as is the din of arms that strikes the ear of the soldier at the front?" "Precisely. Such a description may even be a more significant aspect and part of the sanguinary event than many less remote phases of it are. It is not poetry but strict scientific fact to say that a picture is an aspect determined merely by a more WALTER BOUGHTON PITKIN 223 complex set of relations than the commoner aspects are. A landscape in oil before me has had to work its way farther and more laboriously through vari- ous media than would the original scene. All the intricacies of a sensitive, selective human organ- ism interpose to modify and transform the former in a thousand different ways ; and then there are all the influences of paints and brushes likewise working to make the more ' artificial ' aspect differ- ent from the simple perception of trees and mead- ows separated from the eye only by a span of lighted air. When I consider all this, the difference be- tween pictures and aspects appears to be only a relative one, adapted to many practical ends, no doubt, but not suited to epistemological purposes.** "At any rate," insisted the physicist, "you rob the word 'picture* of all its natural meaning by making representations really, in the broadest sense, pictures of absolutely everything contribut- ing to their production: Rembrandt's portrait of himself is, to you, also a portrait of the brushes he painted the canvas with. Is this not the rankest quibbling?'* "Such extreme cases do make my theory sound absurd. And yet, remembering that the specific pictorial function of anything depends directly upon the character of the spectator's knowledge, and hence upon the attitude the spectator can and does take toward the perceived thing, I cheerfully grant your interpretation. I cannot think it a mere 224 WORLD-PICTURES figure of speech to say that a mind deeply versed in technique might find in the disposition of paint on Rembrandt's canvas a representation of the master's brushes quite as distinctly pictorial as is the splash of gray which we call a cloud in a painted landscape." After a pause in which the learned men and some of the sorcerer's deluded followers com- mented on these words of the teacher, the physicist found an opportunity to speak again. "You have almost won me over," he confessed. "But one more question which interests me as a student of matter. You say our experiences may be aspects or phases of real objects. You mean, then, that trees and stars actually get into our minds .?" "Yes, but not as a rat crawls into a hole. I hear some crying *Topsy-turvydom !' They cry this only because they think I imply that an ob- ject is the same wherever it is. If a thing is defined as what it does, it must be located wherever it acts ; but this does not mean that its nature and powers are the same at every point in its whole 'sphere of influence.' A dog is both at his tail and his nose, yet he is different at each point. If you want to worry yourselves into a madhouse trying to explain how the same thing can be different, do so for all me ! But I have no taste for the game. This same * differentiation and specialization,' so familiar to us all in organic life, appears in every object WALTER BOUGHTON PITKIN 225 as soon as we define things in the broadest, most inclusive manner. The colors I see, the heat I feel, the sounds I hear from moment to moment, the joy that stirs me, these are all proved by physiology and psychology to be manifestations of real things or systems of things. Now, whether or not all influences emanate from certain spatial centres we need not trouble to decide just now. It is enough to say that those things in space which can be connected with these mental things are most conveniently regarded as the ' true ' centres of influ- ence. Thus, speaking exactly, we may say that the sun itself gets into consciousness, provided we do not identify the whole star with the mass of gas at the centre of our planet's orbit. The sun ex- tends far beyond its outermost fringe of quivering molecules, out into the most distant and unimag- ined abysses of the universe, wherever its ether disturbances reach. Only a series of practical abstractions has led men to narrow its bournes to the central fire; the crude animism of the savage who thinks of the sun as reaching down from the heavens, caressing the flowers, stinging men with its heat, and summoning the mists out of ponds is far better philosophy than the over-refined dis- sections of the metaphysician who writes thick, foolish volumes trying to explain how a ball of incandescent gas ninety-five million miles away can become an object of knowledge at a point where it is absent." 15 226 WORLD-PICTURES "Or how a mental sun can get ninety-five million miles away from its parent brain!" inter- jected a sorrowful youth who had taken a course in psychology. "But both the savage and the philosopher com- monly make the same mistake of interpretation; the philosopher does so deliberately at the outset, the barbarian comes to it innocently. I refer to the error that the whole nature or 'essence' of the sun is present in every act of the sun; that, for instance, when the sun is in somebody's mind, it is there in precisely the same sense as it is in the heavens. This notion makes the savage call his dreams the spirits of the things dreamed of; but it prevents the over- cautious metaphysician from believing that the 'real' sun can possibly be known. While the savage is the victim of his own imagination, as a result, the metaphysician is only too frequently led to call knowledge *epiphenom- enal,' 'purely ideal,' or by way of compromise with the overwhelming evidences of realism in daily life, *a symbolic function.' I respect the savage's error, but think the philosopher's unpardonable." "Your philosophy," interjected a logician, "may be sound for aught I know ; but it forces upon you a weird definition of a 'thing.' Every discernible, or if you will, every real, must be defined in terms of and identified with its activity, or, more broadly, with the part it plays in the whole scheme of things. As all things known to man are found only in highly WALTER BOUGHTON PITKIN 227 complex interaction, it follows that for philosophi- cal purposes each thing must be defined in terms of the influence it exerts in all situations wherein it is involved. Every definition founded upon any- thing less is abstract, partial, and at best only adapted to special practical purposes." "Precisely,'* the sorcerer acquiesced. "As any practical man would say, my definition of a thing is good for nothing in particular ! But this seeming reproach does not distress me, inasmuch as episte- mological dictum is not supposed to serve any end commonly called practical." "Rank Relativism!" somebody muttered. The sun is really green because colored glasses make it appear so ! Anything is anything that any- body can imagine it to be ! Reality is nothing more than formless potentiality, mere vXrjy to be moulded by mind." "That last remark is utterly false!" returned the sorcerer warmly. "Such a conclusion is possi- ble only by assuming what I expressly refuse to, namely, that things are nothing but their appear- ances. The character of appearances is deter- mined largely by many things not appearing. So far as my little fancy about world- pictures is con- cerned, the whole structure of the universe may have been foreordained, or on the other hand it may be still in the making. With nothing save a theory of experience to guide us, I do not see how this question is soluble; and for the purposes of 228 WORLD-PICTURES epistemology, it is irrelevant. But Reality surely is not vXt^." "And yet," interjected a bystander, "you say we make our world-pictures. We pick up colors and noises and work them up into all manners of theories, whims, and plans." "True," the sorcerer returned. "But this is only one aspect of the knowledge process. There is another equally important one. Reals get into consciousness, and the reals getting in are world- pictures, representing part of the nature of Reality. The notion that two incompatible theories are here thrown together arises from the fact that the knowl- edge relation may be, but usually is not, considered, like every other relation, from the standpoint of any of the objects or factors involved in the rela- tion. Remember that all factors contribute in some manner to determine the result. Looking at knowledge from the standpoint of the things that succeed in forcing themselves into knowledge, I should say without fear that the objects have *made themselves known,* — that is, have developed em- pirical parts or phases. Looking at the same pro- cedure, though, from the standpoint of all the other factors involved in producing and interpreting the simple experiences which come to be known as aspects of reals, I think it fair to say that * predispositions,* * purposes,' and 'associations* in- terpret the instreaming characters, making them mean aspects of particular reals. But if this is WALTER BOUGHTON PITKIN 229 a mystery to you, I beg you to think it over at leisure. For fast debate solves no puzzles but only arouses thought.'* "You have uttered many true words," said the physicist in behalf of the learned men, " but we still suspect that you have dazzled us with subtle analogies. Our logicians, though, refuse to let us continue the argument by attacking your use of poetic comparisons, for they are of the opinion that perhaps all reasoning is based upon just this sort of analogy with which you have been interesting us. Rest assured, though, that in due season we shall return to this debate. Then, perhaps, the outcome will be decisive." This happened long ago. The learned men have not yet come back to the market-place where the throngs of untutored minds still talk in the tongue of the sorcerers. And nobody knows why the conversation has never been resumed. For all those who heard the debate said that many things remained to be spoken on both sides. But perhaps the disputants have found too many more important things to do. NAIVE REALISM: WHAT IS IT? NAIVE REALISM; WHAT IS IT? By Dickinson S. Milleb I \JF the most recent tendencies to be observed here and there in metaphysical speculation there is one at least clearly healthy and hopeful, the impulse to return to "naive realism." A feeling has arisen amongst certain philosophers akin to what the cultivated world without has long felt about the whole industry of their class, an im- patience of the extravagance of theory that marks the most irresponsible of the sciences, and has marked it not least in the last century; a sense that though ingenuity and speculative enterprise and architectural instinct and the taste for sweep- ing views are at their strongest there, not so much can be said for sanity of judgment or intellectual poise. We have been told, for instance, that Real- ity is Obligation, the obligation to think our world in a certain manner; or that all we can know of it is that it is not like Appearance, the world our thoughts inhabit; or that it is all energy, or all will, or all idea; just as in objective times it was all fire, or all water, or all air. One category- ass 234 NAIVE REALISM after another is cast up before the attention of the time, and the different intellectual appetites seize upon their own. This is so in its measure in every science, but philosophy has the longest circuit to make before it must face the facts that will take no denial ; and thus there is room for the army of Privatdocenten and their elders, who write books of which the first part consists in a refutation of all previous theories and the second in setting forth the next theory that the subject will bear. Philosophy is gone so far round the circuit that for some per- haps to embrace naive realism is only one more tour de force; but for others it is to renounce the splen- did follies of speculative imagination, and return to intellectual seriousness. But the way back to naive realism is not so plain as one might think. Naive realism being the view natural to all of us in all but our philosophic moments, our philosophy should find it close at hand. Yet between these two spots on our own premises the way is apt to be lost. That is to say, to give an accurate analysis in the terms of philos- ophy, a true theoretic rendering, of the deliverance of our consciousness about the external world is so far from easy that the chief schools of philosophy differ in it, so far as they attempt it at all. It must not be forgotten that Berkeley declared himself at one with the plain man and at issue only with the philosopher "debauched with learning." Thereupon Reid and his successors, treating DICKINSON S. IVOLLER 235 Berkeley's doctrine as preposterous, and taking little note of this particular claim of his, under- took to vindicate against him the natural reaUsm of the human mind. Hume, in essential sympathy with Berkeley's method of thinking, disallowed his claim in regard to the plain man, and gave a new account of the plain man's notion, which notion he admitted however to be unphilosophical. German idealists have in general been content to leave the plain man behind; yet if challenged they too would mostly have said that they had no quarrel with his notion. In English philosophy again, it is perhaps not always remembered that Mill's resolution of matter into "permanent possi- bilities of sensation" was intended as psychology as well as philosophy; not only as an account of the facts, but as an analysis of our instinctive view of them. Clifford, on one side at least of his theory, has the same intention. Most of these philosophers, then, have not felt that they were estranged from naive realism at all. It has been left to their opponents to feel it. Now it is at least possible that to fix our minds on the question in what character matter naturally appears to us may forward us in solving the prob- lem of what matter is. In partial measure the former question is considered: metaphysicians study the perception of matter. But they do not with an equal scrutiny study its apperception. Of course we cannot do the latter without the 236 NAIVE REALISM former; so that in the following we shall be partly on thickly trodden ground and partly on neighboring ground that is less frequented. Be it remembered that whatever profit may accrue to our metaphysics, the immediate aim here is psychological, the analysis of an instinctive conception. Consider first the account given by long-estab- lished realistic systems of philosophy. They seem to say that the initial blunder of the idealist is in supposing that to the perceiver consciousness pre- sents merely a "content," an opaque wall as it were with a painted scene upon it. Our con- sciousness in perception is not a mere possession of ours whose import ends in itself; it is con- sciousness of something; it is not a wall but a window; through it we look out upon a world beyond. This, they say, is the distinction of con- sciousness from other things, the unique property that makes it consciousness, namely, that it tells more than it is. The things beyond are not pres- ent in consciousness ; they are present to it. These correlative prepositions "of" and "to" which are so fundamental in our language about experience are expressive of a unique relation. That there is an object distinct from the percept, says a philoso- pher, "is not an opinion about perception, it is the opinion of the perception itself." The opinion may be wrong; in that case perception is illusion, and the naive realist is duped. DICKINSON S. MILLER 237 This runs smoothly enough in metaphor and colloquial terms; and its natural ring proves that it must in some sense or measure be true to ex- perience. But in what sense or measure? 1. A perception, it is said, professes to reveal a distinct object, i. e., it makes consciously by its very nature what is called a transubjective refer- ence thereto. That the perception is not the object is part of the perception's deliverance; it points the attention on to the object; "not unto us" say the perceptions. But this is demonstrably false. The demonstration is psychological. To distinguish something from our perception we must know the perception as such. This may mean either of two things. It may mean that the perception is conscious of its concrete self (if these words have a meaning) and distinguishes that from the object. But a glance of introspection shows of course that we are not conscious of any perception apart from the object. Or the theory may mean that we distinguish the object from perception in general or from consciousness in general. To do this we must have formed an idea of consciousness in general or of perception in general, and a distinct idea; and that "the child, the rustic, and the savage" have not done; nay, the financier, the general, and the senator have not done it; only the psychologist and a few others have really made the attempt. The theory asks that every man's mind should in every min- 238 NA'lVE REALISM ute do what philosophers in the centuries have not yet definitively done: distinguish in generic nature between object and perception. Besides, if introspection shows that we are not conscious of the concrete perception apart from the object, it shows as well that we are not abstractly think- ing of its nature thus apart. A conscious tran- subjective reference does not then arise in sense. 2. It turns out that " a conscious transubjective reference " is a phrase without meaning. To say that the reference of a mental "content" to its ob- ject is contained in the mental "content" is a natural warping of language, but it is a confusion of ideas. One existence may resemble another, but (by the force of the terms) it cannot contain what is truly another, and if it contains a "sign" or "in- dication" of it we must remember what signs and indications are. They are always facts, individual in themselves, which lead the mind to another fact because they are associated with it. A pic- ture is a picture of a man because, it being like him and I having seen him before, it carries my mind straight to him. A flag stands for a coun- try's name and honor because being long coupled therewith it suggests them at once. But a flag is a piece of bunting and a picture is canvas and oils. The connection is made in my mind, which carries between the two, and the words reference and meaning are used for the relation thus created. The like is true of words themselves and gestures, DICKINSON S. MILLER 239 with their meanings. The meanings are associa- tions. Indication never lies wholly in the indi- cating thing; it is a function of that thing, the fact that the thing works suggestively through the mechanism of the mind. This suggests a difficulty to be sure if we should come to the case of a man's thought of other men's minds or of his own past experience. Indeed the chief argument for the conscious transubjective refer- ence is that we could never have knowledge or thought beyond our mind if it did not exist. The argument does not directly try to make this kind of reference credible ; it is an argument by threat. But I am not denying reference at large; only self- reference, or conscious reference, a reference which is not only a logical function but a psycho- logical datum. And I cannot here pass beyond the problems of perception. Wherein then is this realistic account true to experience ? In its saying that in perception we recognize that the object is external to ourselves. We do recognize this; at least we are always ready in perception to recognize it at the slightest need; but "external to ourselves" does not mean external to our consciousness (as has often been pointed out) but external to our bodies, pri- marily, and, secondarily, distinct from our feelings and ideas. We can now take one step forward. In percep- tion we recognize an object. We do not recog- 240 NAlVE REALISM nize a perception. After the fact two rival theories arise. One tells us that the object was really to be classed as a "content of perception" only. The other tells us it was a fact distinct from our con- sciousness. Whichever of these is the truth, we did not know it at the time. Now by naive real- ism we mean the attitude of the ordinary mind toward the external world. We say, then, that, when in the presence of the ohjecty naive realism takes up with neither of these theories, but simply finds an object, of particular quality and property ; the objectivity itself being resoluble into features of this quality and property; such as independ- ence of the perceiver's will, location in space, membership in a trusted order of experience, and the rest. But in retrospect (it may reasonably be asked) does not the view of naive realism become differ- ent? When we look back on ourselves, even in irreflective memory, as having perceived a real object, do we not distinguish the object from our perception ? The contemplation of our past selves as perceivers, however, is so much like the con- templation of other men as perceivers that the two are best considered together; as they will be presently. Turn now from the traditional "realistic" ac- count of naive realism to Berkeley's. It is chiefly when speaking of objects while they are per- ceived that Berkeley claims the support of the DICKINSON S. MILLER 241 plain man. And it follows from what has just been noted that at least the plain man does not contradict him. Berkeley passes beyond the plain man in classing the present object as "idea," that is, content of consciousness, because imme- diately present. The plain man does not class it metaphysically at all; but the plain man does regard it as immediately present. Hence in this large department of the subject there is no con- flict between them. I think this will be recognized without need of our lingering over the old miscon- ception; namely, that Berkeley somehow took away from present objects their substantiality or their objectivity. Even Professor Paulsen, to be sure, despite his idealism, is found asserting that unless objects have something apart from our consciousness to support them (psychic life of their own, he would say) the theory becomes Illusionismus. It is one more instance of a thinker performing an analysis and then shrink- ing from the conclusion, slipping back into the old unanalytic language before he comes to record his result. Both Berkeley and the plain man regard the present object as really there, really placed in a portion of the space that appears; both regard it as outside the body of the per- ceiver ; both regard it as distinct from his feelings and his ideas, in the vernacular sense of the latter word. 16 242 NAIVE REALISM II The real difficulty in reconciling the two views appears when we think of unperceived objects. Here also, however, Berkeley will admit no differ- ence. The three distinct explanations he gives in different passages of what the unperceived object really consists in he attributes directly or implicitly to the plain man as being his theory also. In these explanations, briefly given, we can see the germs of ideas that have figured con- spicuously in the subsequent history of philosophy. Let us look at them first as he offers them, though it will be convenient to take them in a different order from that in which they are found scattered in his writing. First, the absent object exists because, though I do not perceive it, I think of it. It has the same claim to reality as a perception, being like that an "idea," a content of consciousness. Second, the absent object, indeed the whole material uni- verse, exists as an idea in the mind of God. Third, the absent object exists in the sense that if I induce the train of perceptions called going to the spot, etc., I should perceive it. The flaw in the first is that it affords no ground for distinguishing, as naive realism distinguishes, between false thoughts and true thoughts about absent objects. The flaw in the second is that DICKINSON S. MILLER 243 we think our physical world simply, and not as bound in unity of consciousness with the subjec- tive background of a divine mind. The flaw in the third is that, though it is quite true that we derive our materials for picturing things not now perceived solely from former perceptions, yet when I believe they exist now there is no "if" in my belief. Yet though these suggestions so plainly fail us as Berkeley put them, yet they are susceptible of such development that we shall not wholly lose sight of them again. In part they have acquired this development in the course of subsequent thought, though not always with direct debt to Berkeley. Let us return to them in a developed form. The first explanation becomes nothing less than one phase of the thought of Fichte, of which Professor Windelband in his early volume ^' Pra- ludien," and Professor Rickert in " Der Gegen- stand der Erkenntniss'^ have made so acute and incisive a restatement. The distinction to them between true thoughts and false lies not in their relation to independent outer objects which thoughts are called on to resemble, but in relation to an inflexible law which they are called on to fulfil. This conception in Fichte was of course a pursuance of Kant's description of the outlying phenomenal world as a construction "according to rules," the "lawful context" of present expe- 244 NAIVE REALISM rience. Professor Windelband tells us in his re- markable speech on Kant that human thought has yielded two radically different conceptions of that in which the essence of knowledge lies, the Greek conception and the German. The Greek still dominates most of the world. According to it, to know is faithfully to picture a fact distinct from the knowing. According to the German, of which it was the genius of Kant to lay the foundations, to know is to feel and follow an obli- gation of thought as such. In his essay on Nor- men und Naturgesetze he points out that there is an "ought" equally in thinking, in acting, and in judging of beauty. He dismisses metaphysics as "em Undingy" which frivolously concerns itself with the mythical originals of our thought; and leaves us logic, ethics, and aesthetics as the three departments of philosophy, all mandatory or normative. To which Professor Rickert naturally adds that the category of obligation, as compared with that of being, is seen to be prior and profounder. In this, we have got far beyond Berkeley. Berkeley denied a transcendent reference as re- gards present things; it never occurred to him to deny it as regards other spirits, the spirit of God, for instance, nor yet as regards the object or "ideas" that they perceive. It is the esse of things that is percipi — the things of sense. Yet we have seen how the idealist tendency, begun in that lim- DICKINSON S. MILLER 245 ited field, urged occasionally further and led him to drop what I have called his first remark about absent objects — it may have been almost inad- vertent — that the unseen fountain existed, since we thought of it. Meanwhile Fichte and his followers have no trouble about unperceived objects, just (they would say) as the naive realist has no trouble; though they go further than he in theoretic speci- fication, they go side by side with him as far as he goes. Of course we believe in the outlying stretches of the physical world, they would say; that is the way we have to make up our world in consciousness. The perceived object is sensory; the unperceived object is given in the different stuff of idea; but they are both given, or made, and there is no perplexity about one that there is not about the other. Do not these teachers, however, in their zeal of theory, prove too much for the gain they have in view ? For this way of describing knowledge must apply to our knowledge of other minds; to halt at that point would be fatal ; the view must com- pass all the world or none. And if we include other minds, then the world appears with " streams of consciousness" in it, isolated, each one, from all others, believing each in the separate other, each with the present physical object given and the absent object conceived; each confronting the question whether the absent object shall in thought- 246 NAIVE REALISM f ul conception be held real in the same sense as the separate minds or its own past. In other words we have our world over again with all its difficul- ties. These thinkers would draw the universe through the circlet of the knowing consciousness; it is their triumph in their own eyes that they draw it all safely through; but the result is that they have not left even the difficulties behind. Most plainly, our own problem stands just where it did before. The objection is not now what it was to the germ of Professor Windelband's doc- trine as that germ lay in Berkeley's writing; the doctrine does not now deprive us of a distinction between truth and error about absent things. The objection is that it is too wide a principle to tell us anything about the special problem of ab- sent physical objects at all. Let a thing be "real" for us if we are under an obligation to think it : we must still ask, are we under an obligation to think of absent objects as real in the same sense in which, for instance, we think of other minds as so. If the answer is yes, then we are metaphysical realists and not idealists at all. If the answer is no, naive realism seems to go by the board. The doctrine tells us something about the forum or sphere of thought (I need not ask here what mean- ing is left in its description) ; it tells us nothing about what shall occupy it. It tells us perhaps something about the canvas and the pigments, but nothing about the features of the ideal scene. In DICKINSON S. MILLER 247 the ideal scene are separate minds that think about each other. Representation then is an inexpug- nable fact in this world, implicit in the philoso- pher's thought as in his questioning reader's, and at the end of all idealisms, at the bottom of the most German of philosophies, Greek meets Greek after all. Next we turn to the development of Berkeley's second device for accommodating absent objects, that of lodging them in the mind of an Eternal Spirit. This theory has been taken up since his time; it has been remarked, for example, that if a flower is "born to blush unseen" it is unseen only by men ; it has its existence through entering into the divine experience. We are interested in this only as it bears on naive realism. Suppose we simplify it by omitting from the mind thus sug- gested the background of personal will and feeling that theologies may attribute to God. There re- mains a consciousness in which the whole span and detail of the material universe is presented, and so far nothing else. Further I shall have to assume here, without reasoning, that what we call consciousness is nothing but what psychologists call "contents," together with the relation of joint presentation, or let us say simply empirical conjunction, that exists between them; the so- called subject or unity of consciousness being re- soluble into this ultimate relation. Conceive now that this complete and duly joined "content" of a 248 NAIVE REALISM world, of quality like ours, has also property and process like ours ; that from moment to moment it changes, its parts move, and then rest, just as mat- ter does for the naive realist. Let the naive realist think of his physical world in its entirety. Let us think of this other sort of world. What would be the difference between the two ? Would there be any ? Hume would have said, none. I turn again to familiar history, for we are trying to find the meta- physical conceptions that lend themselves to an instinctive way of thinking; it is not always easy to see how such conceptions operate ; so we go for instruction to the workshop where they were slowly forged and put together. Hume wrote: "All ideas are borrowed from preceding percep- tions. Our ideas of objects, therefore, are derived from that source. Consequently no proposition can be intelligible or consistent with regard to objects, which is not so with regard to percep- tions. But 't is intelligible and consistent to say that objects exist distinct and independent.'* Which means, to Hume's thinking, that it is intelli- gible and consistent to say that perceptions exist in detachment from personal minds. "This," he says, "is the doctrine of the vulgar, and implies no contradiction." If the vulgar doctrine is right, then, the immediately given object looses itself from our consciousness as our body turns away, but continues in existence and in its place in the DICKINSON S. MILLER 249 ordered world. It will be seen at once that this justifies the naive realist as to the direct presence of the given object, and as to the reality of the absent object, without the disconcerting "if." And there is an amendment that suggests itself which would justify him still further. For if such a colossal "content" or perception would be identical with the physical world of com- mon belief, what is the point in calling it "con- tent" or perception or mental at all.? We have apparently found ourselves able to state the com- mon belief in "idealistic" terms; but at the in- stant of junction between the two does not the idealism cease to be such ; cease to retain any dis- tinguishable meaning? Vse receive back our world, in which the streams of personal impres- sions are only a part, and in which the solid and continuous world stretches between. Shall we not then say that Berkeley did a service in showing objects as immediately present, and that the steady push of Hume's penetration removes all that was paradox and hard saying in Berkeley's system, giv- ing us common sense again, philosophized ? Since the distinction between consciousness and matter was the distinction between the streams of personal impressions and the independent world, no heart of meaning remains in calling the whole mental. Well, this seems a broad landing-place for our thought. But even this does not prove an abiding place. There are reasons for moving further. 250 NAIVE REALISM When Hume said there was no self-contradiction in saying that a partial content separates itself from the rest of my content and continues to exist alone, he was surely right. Conceive the whole material worldy however, as a great content existing thus, and it becomes evident that the objects now pres- ent in my own field of consciousness must be du- plicated in the world- content. Yet naive realism does not think of presented objects as duplicates of complete objects unpresented. Shall we take refuge in saying that to the extent to which objects are presented to me, I actually share the physical world- perception ; that the whole matter- content is not my content but that certain bits of it momen- tarily are ? This seems a contradiction in terms. It would be to say that an identical content can be in two fields of consciousness at once. Try to sup- pose a content X in two minds or fields one of which contains also the private content A, and the second of which contains also the private content B. Joint presentation or empirical conjunction, that which constitutes a field, is a relation between contents. Now in field No. 1 X stands in a rela- tion of conjunction with A, while in field No. 2 it does not stand in that relation, A being left out- side. So the result is that the same content, at the same time, does and does not stand in a certain relation to another. Ah ! but, it will be said, add the amendment that suggested itself. Do not call the material DICKINSON S. MILLER 251 total a content, call it simply a material total, across which the little spots of consciousness flit without disturbing it. In that case the relation of con- junction in a field would be a momentary relation between objects, which when they passed out of that field they would bear no longer, ^Yith this change of words, however, the obstacle really remains as before. But another obstacle of the same order can perhaps be pointed out more briefly. Anyone who should accept such a view must hold also that the same object or part of it might be presented to two human minds; otherwise there would be a duplication repugnant to naive realism. Here is the self-contradiction again; and I agree with Hume that we cannot ascribe such a contradiction to the famihar, constant thought of ages. Thus even in their developed forms Berkeley's first and second conceptions of the unperceived object fail us as interpretations of naive realism. In approaching the development of the third it will be necessary to consider deliberately what we mean by "consciousness," a term which according to the tradition of English philosophy I use in the same sense as "experience." Ill When I survey the things about me, my natural associations are physical and topographical, for the movement of my organs of sense has so repeatedly 252 NAIVE REALISM made that sort of connection. From the side of the peach turned toward me I have looked round it to see if it was sound; I have presently cut it open, taken out the stone, seen the red fibrous tissue that had been about it, and the flesh of the peach. When I enter a room a large desk may hide much of it from me, but as I come forward I open up, as it were, part after part that was hidden. When I look at the desk a foreshortened aspect of one side appears to the eye, but I open it, sit down, pull out a drawer, look into a compartment, take up a memorandum-book, turn over pages, and so in a hundred obvious ways draw new perceptions from what I call the desk and its contents. I had en- tered the room from the house and the house from the neighboring places ; and all these tran- sitions effected again and again have left their strong impress on my tendencies of association. If I should stop myself on entering the room in a fit of self-cross-examination and ask myself what the desk, of which but one side shows, foreshort- ened, really is, my thought would pass rapidly to its writing- surface, its store of writing-materials, and the rest. If I try to take in a larger part of things my thought will be likely to pass to the whole room, the house, the neighborhood, the city, state, country, globe. That is what I mean by my thought's ranging topographically. There are, however, other physical associations besides those of neighborhood. Loosened screws may suggest a DICKINSON S. MILLER 253 screw- driver which is far away, or a carpenter who is farther. (A carpenter, be it said in passing, is for most of us in most of our moments a purely physical tool, comparatively self-acting as com- pared with the screw- driver.) Or a ball may carry the mind to a game in open country, or the fields to the ball, or a chemical compound to its compo- nent parts, or stones to pavements. In all this we are led from idea to idea or from percept to idea along the paths of perceptual succession or the paths of familiar thought about perceptions. This is objective association. Of such is the mental stream of most men, and even though they may ex- perience or think of emotions and desires that color their percepts and ideas, yet these, though they are the motive power, are not so often the pivot of asso- ciation. When they are it is for a moment, to start the mind in another objective train. Now for some human beings at some times, for a very few human beings often, there is quite an- other kind of association. We sometimes try to attain it, though not very exactly, when we are trying to remember where we put something lost. We remember that we noticed the open desk five minutes ago. We try thereupon to remember what we did or noticed next. The contents and uses of the desk may come up to the mind with the importunity of custom, but we thrust them down ; in psychological language we inhibit them by fixing voluntary attention with effort on the 254 NAIVE REALISM idea we wish to keep: the desk just so far as we noticed it, as it figured in our personal experience, at that moment; for we hope it will call up what figured next (another object noticed, words heard, a feeling roused, a plan suggested), and so bring us in time to the forgotten action. The usual aver- age sequences that keep offering themselves we keep excluding ; what we invite is only the sequence that obtained on a particular occasion. The introspective memory of the psychologist is but an effort to make this same difficult selective association exact. The difference between it and the objective association is the difference between thinking about consciousness and thinking about matter. It is one of the two sources of the distinc- tion between consciousness and matter themselves. The other exists in the phenomenon of my fellow- man. His body is an object for consecutive per- ception like the desk; but I cannot find his perceptions in it ; nor yet his feelings, willings, or ideas. If I want to realize his view of the desk, I must note his position toward it, and try in idea to see the desk in that aspect. All that belongs other- wise to the desk I must keep out; I only want what he saw or thought of ; in other words I must now practice toward him in imagination, without the aid of spontaneous memory, the kind of selec- tive association I employed to bring up my own past experience. This points us at once to the nature of con- DICKINSON S. MILLER 255 sciousness in contradistinction from the nature of matter. I refer to matter as it figures in our natu- ral view of the world, in the vernacular of thought. Matter is a thing of many aspects, consciousness has but one. Matter is permanent, the content of consciousness fleeting. The difference is not one of stuff, quality, or simple kind. The power of thinking persistently of conscious- ness in its single aspect, which is its whole being, may be called the Psychological Imagination. It is of course very rarely found and can only be es- tablished by arduous practice. Clearly it must think of consciousness never as an object, for ob- jects have many aspects, to be explored in succes- sion; but always subjectively, as it comes. The being of a feeling is its being felt. Consciousness is the realm in which appearance and reality coin- cide. In this, of course, the single state or field of consciousness is meant. To think of such a field justly is to think of it just as it seems. It has no hidden nature, no underside, no central substance or kernel, no interior recesses to be explored. All that order of appurtenance is confined to matter, which reveals aspect after aspect to the advancing percipient, each aspect as perceived being called, when the psychological imagination seizes it, a con- tent of consciousness. A consciousness may be in the given case a spatial content, but not being an object it is not in space. We cannot expect ever to discover it, to say "Lo here," or "Lo there" of 256 NA'iVE REALISM it. It is nowhere; a reality to which location is irrelevant. For itself it does not need to be dis- covered; in other fields of consciousness it can at best be represented. Returning now to naive realism, shall we say, as above, that for it the whole of the physical world has, like consciousness, an ultimate and irresoluble existence ? Impossible. Not even for the naive realist. For matter is a realm of aspects and these aspects, congenial enough in succession and alter- nation, will not fit together to form in one total a coherent world. The desk as a light- brown total or unit, the desk as a complex combination of drawers and compartments to the right and left, the desk as a wilderness of woody fibre, the desk, if you will, as a host of ordered molecules or atoms, are different desks, and will in no wise go together. I have spoken of the problem of present objects and the problem of absent objects. But every present object is partly absent; integral aspects of what we should call the object are unper- ceived. In perception we have one aspect, en- larged with a few strokes by peering imagination to represent the rest. For the foreshortened view we half substitute the normal view and under all is a depth of the tactual and kinsesthetic order. But if we could bring in all sides and features of the object we should not have a desk, but a monstrous medley. If the divine mind tried to vergegenwdrtigen all matter at once, it would have. DICKINSON S. MILLER 257 not one picture, but a multitude of models on all scales. And precisely because this supposed "content" would really, in kind or stuff, be in- distinguishable from the plain man's matter, the plain man's matter is subject to the same con- ditions. The incompatibility is logical. A con- tinuous polished brown surface is not a fibrous or a granulated surface. A marshalling of what we scientifically mean by molecules is not what we familiarly mean by a desk. It may be said that we must on reflection let the desk go and keep the molecules. In that case we should have to ask whether the same diflSculty did not apply over again to the various aspects of the molecules. But we need not, for our subject is naive realism, which will not let the desk go, and yet recognizes no diflSculty in keeping both. The problem, briefly, is this. Can all the as- pects of matter be compacted into what may be called one aspect ? A mind that fully knew them, knew them even representatively, would know them so. And would this joint aspect be acceptable to naive realism as its world in sum ? That is the test. If not, then we cannot say that naive real- ism regards its world as all concurrently real in the ultimate sense of that word. It is debarred from doing so by inability. Of course, as we saw, the common conscious- ness has no "if." Really to think an "if" means to think in some form an alternative. But when I 17 258 NAIVE REALISM represent unperceived aspects there is no practical need of representing any alternative to their ap- pearing each in its due place and turn. Let us admit it at once: naive realism does not bother itself to carry any idea about with it that is not essential for practice. My only reason for not accepting naive realism as a sufficient metaphysic of matter is that there is no such theory. It is more naive than we thought. All there is of it is acceptable. One phase of what there is of it is the flexibility of the conceptions with which it works, its ready submission to the substitutions of expe- rience, the ease of mind with which for the moment it is off with the old and on with the new. The revealed aspect of the present object is for us a sign of aspects that might come. Now the naive realist's notion of absent objects, being got from them when they or their kind were present, is always as much like his impression of present ob- jects as possible. The aspects of absent objects that he represents in his thought of them are signs of the other phases in reserve. Just as he does not label them as mere signs when they are percep- tions, so he does not when they are ideas. But their function and utiUty are to stand there in his mind as signs of more. When we so recognize and class them we do not undo naive realism, we only interpret and complete it. In other words, naive realism does not of course deny in its own thought that the aspects of its world are in the DICKINSON S. MILLER 259 strict sense concurrently real; it merely omits any affirmation on the subject ; leaving it to metaphysics to perceive that they could not be. The truth is that if we would understand our natural notions of the external world, we should ask ourselves, not what we think about it, but how we think about it ; not what verdict do our judg- ments give, but what is the nature or method of judgment on the subject. We have not yet thrown off the tyranny of language. We still expect to find a judgment built like a sentence, and an idea packed with all that is mentioned in the definition of the term we have for it. But the elements of thought are fragments with forces, and a definition tells merely the ideas that are recoverable by the mind at need as justly pertaining to a term. Put your questions to the rustic or the child or your naive self, and they will discourse fluent language in reply. The difficulty does not lie between the subject-matter and their answers, but between their answers and their ideas. Not that there could be any more apt expression of their ideas, but that the metaphysical cross-examiner may not understand the laws of expression. A little advance upon naivete is a dangerous thing. About natural real- ism we have just reached w^hat seems a sore ex- tremity of paradox; but then when language is confronted with thought, as thought is seen by the psychological imagination, paradox is the invariable result. 260 NAIVE REALISM Berkeley's third explanation of the existence of unperceived objects was developed in the doctrine of Mill that they are permanent possibilities of experience, and Mill attributed this view of them to the ordinary mind. Our business is with the ordinary mind only, and our conclusion brings us into the neighborhood of Mill's. (1) The stuff of which unperceived objects are made in our thought of them is of course solely the stuff of ex- perience; (2) this stuff is never compacted by our thought into '* whole objects," all the aspects of which exist together, as philosophical realism re- quires; (3) however, the fact that the aspects do not so exist together is not consciously recognized by our thought, which merely takes them in turn without trying to put them together and thus test their compatibility. The fact that we never try to weld all the aspects into one is the very reason why we do not know that they are incompatible and are surprised when we are told so. Unperceived objects then are possibilities of successive experi- ence to us, as they figure in our natural thought, but Mill was mistaken if he meant that we class them as such.^ Our problem in its totality has been double: what is naive realism in its belief about perceived objects, and what is it in its belief about objects * Very likely he did not mean this. Perhaps hia language only marks the fact that he had not sufficiently separated the problem of naive thought from that of philosophic truth, or thought the former problem out in the respect in which we have last been studying it. DICKINSON S. MILLER 261 unperceived ? These terms, however, have been coarsely used and need analysis. In one possible sense no object is perceived. Most of what belongs to its integrity, and to its character as that object, does not appear in the perception. Should we then speak only of perceived aspects and unper- ceived aspects ? No, for the " one possible sense " in which we here speak of perception is a perverted sense. Properly speaking, perception is the posses- sion of certain aspects flus the preparedness for others. The aspects possessed shade off into vague- ness. The preparedness, considered as a psycho- logical fact, is no doubt partly the associative function of the elements present in consciousness, and therefore not itself present in consciousness at all ; and partly an element of consciousness answer- ing to motor processes half awakened. Perception is a step out into a world of objects, with the other foot held ready, as it were, for another step. Objectivity itself is the potentiality of further spatial aspects, and, these aspects being as we have seen incompatible, the nature of objectivity itself excludes the notion that they co-exist as *' natural realism " turned into metaphysic would require. KANT AND THE ENGLISH PLATONISTS KANT AND THE ENGLISH PLATONISTS By Arthur O. Lovejot A MEMORABLE philosophical discourse deliv- ered by Professor James at Berkeley in 1898 — the discourse in which the term "pragmatism" as the name for a philosophical method was first sent forth upon its extraordinary career — con- cluded with this striking historical generahzation : "I beheve that Kant bequeaths to us not one sin- gle conception which is both indispensable to phi- losophy and which philosophy either did not possess before him or was not destined inevitably to acquire after him through the growth of men's reflection upon the hypotheses by which science interprets nature. The true Une of philosophic progress lies, in short, it seems to me, not so much through Kant as round him to the point where now we stand. Phi- losophy can perfectly well outflank him, and build herself up into adequate fulness by prolonging more directly the older Enghsh Hues." The present paper is a partial commentary upon this text; and it will offer certain detailed evidence for the substantial accuracy of the generahzation in precisely that particular where it may seem at 265 266 KANT AND THE PLATONISTS first sight, and to most readers, to be least plausible. By the generalization, as I here propose to justify it, I by no means understand it to be implied that Kant rendered no useful service to philosophy, nor that he is not historically a figure of exceptional importance. But I do understand the observation to mean — what I also believe to be a precisely verifiable fact — that the Kantian doctrine was destitute of any radical originahty; that none of the more general and fundamental contentions of the "Kritik der reinen Vernunft" were particularly novel or revolutionary at the time of their original promulgation; and that the principal develop- ments of post-Kantian philosophy, even in the os- tensibly Kantian schools, were not dependent upon the historic interposition of the ingenious com- plexities of the critical system, but were clearly present in germ, sometimes even in fairly full- blown form, in the writings of Kant's predecessors or contemporaries, out of which they would in time inevitably have come to fruition. To the general- ization as thus construed I think it necessary, however, to make one exception, and that one of especial interest in the present connection. Kant's doctrine of the "primacy of the practical reason,'* — both in its negative and its positive imphcations, — I take to be the original of a large and diversi- fied class of subsequent tendencies, of which the movement known as pragmatism is (at least in cer- tain of its aspects) one variant. Even this idea was ARTHUR O. LOVEJOY 267 assuredly not new; but I know of no philosopher before Kant who asserted it so definitely and pre- cisely and gave it such place as a central methodo- logical principle. But this one doctrine aside, the text which I have chosen needs, I believe, no very material quahfication. That it seems — as it probably does — to many a glaring historical para- dox, signifies only that the commonly, or at least the popularly, accepted general outHne of the his- tory of philosophy is lacking in any great measure of historical truth. That part of it which concerns Kant's historical place and relations is particularly full of mensonges convenus — as a result, partly, of certain pecuharities of Kant's own mind, partly of certain pecuharities of the intellectual fashions prevalent in Germany between 1780 and 1820, and partly of certain peculiarities of the dominant tra- ditions of the German mind during the greater part of the nineteenth century. In the present short paper I shall, of course, attempt to deal only with a single phase of this subject. The "older Enghsh hues" in philosophy which Professor James had in view in the concluding pas- sage of his Berkeley address were, I suppose, chiefly the British empiricist and sceptical movements of the eighteenth century, and perhaps the Newtonian cosmical physics. That the critical or negative side of Kant's doctrine — its antimetaphysical temper, the positivistic note of the Aujkldrung which sounds so loudly, especially in the Preface of the First Edi- 268 KANT AND THE PLATONISTS tion — is largely derivative from earlier, and chiefly from British, sources, is tolerably obvious, since Kant himself made acknowledgment of his obliga- tion here in a famous and now hackneyed phrase. But, it may be asked, were not the affirmative, constructive elements in the system — the trans- cendental ideahsm and the arguments upon which it is based, the general doctrine of the a 'priori con- ditions of the possibiHty of experience, the assertion of the active functioning of the mind in the deter- mination even of objects of sense- perception — were not these thoughts original with Kant and peculiar to him ? Original they may have been, if by that is meant only that Kant did not actually borrow them from any other philosopher. But essentially new they were not. That they are rather generally supposed to have been so is due partly to the prevailing neglect — sometimes even by learned historians of philosophy — of an interesting and by no means uninfluential movement in Eng- lish thought. The Enghsh Platonists ^ of the later seventeenth and early eighteenth century, though they are not as a rule easy reading, and though they are commonly very deficient in that critical and sceptical temper which Kant had learned from the long discipline of the Enlightenment, are not a neghgible quantity in the history of European phi- losophy. But they have been very inadequately * One cannot properly speak of them as Cambridge Platonists, for several of the most significant metaphysicians of this period and this general school — Burthogge, Noma of Bemerton, Collier — were Oxford men. ARTHUR O. LOVEJOY 269 dealt with by English students of philosophy ; and it is a humiliating fact that, just as, until the publica- tion of the first volume of Dr. Woodbridge Riley's monumental work, the only serious attempt at a comprehensive history of philosophy in America was due to a French scholar, so for a large part of the history of this remarkable episode in Enghsh epistemology and metaphysics we are still de- pendent upon M. Georges Lyon's "L'Idealisme en Angleterre au XVIII* siecle/' Modern and accessible editions of the writings, or of judicious selections from the writings, of most of these early Enghsh rationalists and ideahsts are still to seek. In what follows I shall undertake to present evi- dence for the truth of three observations respecting these English Platonists : (1) that ix^oy anticipated Kant in his so-called "Copernican revolution," and, incidentally thereto, in his general doctrine of a priori mental elements, in his main line of argu- ment for the existence of such elements, and in the pecuhar type of "transcendental" idealism which resulted from that epistemological doctrine; (2) that Kant was similarly anticipated by one of these English philosophers in the employment of the ar- gument from the mathematical antinomies concern- ing infinity and infinite divisibility as a final and definitive proof of the ideahty of the spatial world ; (3) that the most characteristic ideas and tenden- cies of the so-called neo- Kantian school, especially in England and America, are already plainly recog- 270 KANT AND THE PLATONISTS nizable in certain of these English Platonists, so that one is entitled to say that the metaphysical and theological conclusions and the dialectical devices which this school is supposed to have elaborated out of Kantian materials might equally well have been derived from the English idealists of the sev- enteenth century. In undertaking to demonstrate these three points, I necessarily must limit myself to emphasizing similarities ; through the resem- blances to be noted there run, of course, plenty of differences of detail, of mental temper and attitude, of historic heritage. These differences are not less instructive than the analogies, and it would be interesting to scrutinize them closely, if space per- mitted. But in the hmits here available, it seems more to the point to dwell chiefly upon that side of the historical relations in question which appears to be the more frequently overlooked. The part of Kant's epistemology which seemed to him so novel and so momentous that he likened it to a "Copernican revolution'* in philosophy, consisted in the hypothesis that knowledge de- pends upon the "conformity of objects to our mode of cognition " rather than upon the conform- ity of our mode of cognition to objects. This doc- trine that "the world as object is conditioned by me as subject," whether regarded as a daring ARTHUR O. LOVEJOY 271 paradox or as an ultimate truth, has generally been supposed to be sufficient of itself to establish the reputation of the Kantian system for epoch-making originality; and, especially by the literary popu- larizers of philosophy, it has very frequently been looked upon as the supreme example of the profun- dity of Kant's speculative insight. It is, says Mr. W. S. Lilly ,^ "the deepest thought that has ever entered the human mind." However that may be — there is little profit in disputing about superla- tives — the thought is at all events one that had entered a number of Enghsh minds, and had been set forth in more than one widely-read book during the century preceding the birth of the Critical Philosophy. To speak of it as a peculiarly " Kant- ian" contribution to the world's stock of ideas is an historical absurdity; that Kant himself considered it a thing startling and revolutionary is only one among many illustrations of his astonishing igno- rance, or forgetfulness, of all save a very few of the philosophical discoveries and tendencies of his own age and of the generation or two that preceded him. For the English Platonists could not w^ell have been more expUcit or emphatic than they were in insisting that the mind is no tabula rasa but a thing possessing a fixed constitution of its own antecedently to experience ; that, not only in reflec- tive cognition but even in sense- perception, it has an active, and not a merely passive, role ; and that * Fortnightly Review, August, 1906. 272 KANT AND THE PLATONISTS the object is determined by the nature and catego- ries of the mind rather than the contents of the mind by the simple infiltration of ready-made ob- jects. In the most celebrated of the productions of the Cambridge school, Cudworth's " True Intellec- tual System of the Universe " (1678) — a work that has, behind all the quaintness and naivete of its style, a good deal more philosophical acumen than it usually gets credit for — the opinions in question are expounded with characteristic prolixity. Cud- worth and his like-minded contemporaries were brought to the elaboration of this type of doctrine largely by their reaction against the empiricism and imphcit scepticism of Hobbes, to whom their rela- tion was entirely analogous to that of Kant to Hume. I am inclined to think, however, that the empiricism of Hume represented a greater advance — in clarity of thought and force of reasoning — over that of Hobbes, than did the apriorist ration- aHsm of Kant over that of the English Platonists. "We have," says Cudworth, "set it for the elev- enth atheistic argument, that knowledge being the information of the things themselves known, and all conception the action of that which is conceived and the passion [i. e., the passive receptivity] of the conceiver; the world and all sensible things must needs be, before there could be any knowledge or conception of them. . . . For, according to these atheists, things made knowledge, and not knowl- edge things; they meaning by things here only ARTHUR O. LOVEJOY 273 such as are sensible and corporeal. So that mind and understanding could not be the creator of the world and these sensible things, itself being the mere creature of them ; a secondary derivative re- sult from them, or a fantastic image of them ; the youngest and most creaturely thing in the whole world. . . . Now we shall, for the present, only so far forth concern ourselves in confuting this atheistic doctrine as to lay a foundation thereby for the demonstration of the contrary, namely, the existence of a God, or of a mind before the world, from the nature of knowledge and understanding. First, then, it is a sottish conceit of these atheists, proceeding from their not attending to their own cogitations, that not only sense, but also knowledge and understanding in men, is but a tumult, raised from corporeal things without pressing upon the organs of their body ; or else, as they declare them- selves more distinctly, nothing but the activity of sensible objects upon them and their passion from them. For if this were true, then would everything that suffered and reacted motion, especially polite bodies, as looking-glasses, have something both of sense and understanding in them. It is plain that there comes nothing to us from bodies without, but only local motion and pressure. Neither is sense itself the mere passion of those motions, but the per- ception of their passions in a way of fancy. But sensible things themselves (as, for example, light and colors) are not known and understood either by 18 274 KANT AND THE PLATONISTS the passion or the fancy of sense, nor by anything merely foreign and adventitious, but by intelligible ideas exerted from the mind itself, that is, by some- thing native and domestic to it: nothing being more true than this of Boetius, that * Omne, quod scitur, non ex sua, sed ex comprehendentium natura, vi, et facultate cognoscitur : ' Whatsoever is known, is known, not by its own force and power, but by the force and power, the vigor and activity of that thing itself, which knows and comprehends. Wherefore, besides the phantasms of singular bodies, or of sensible things existing without us (which are not mere passions neither), it is plain that our human mind hath other cogitations or conceptions in it; namely, the ideas of the intel- ligible natures and essences of things, which are universal, and by and under which it understands singulars.^* ^ Here, then, we find in Cudworth the good Kant- ian doctrine that even the presented object of sense is what it is because it gets its constitution from the constitution of the mind that apprehends it; although Cudworth, like Kant, intends at the same time to hold fast to an essential realism, and has no thought of maintaining that all that there is to the object is furnished it from the perceiving mind. And for the further Kantian contention that we are able to make vahd universal judgments a ^ " True Intellectual System of the Universe," London, edition of 1820, III. pp. 400-403. ARTHUR O. LOVEJOY 275 priori and that the ground of this abiUty lies in the mind's possession of certain constitutive con- cepts not derived from experience, the pages of the "True Intellectual System" are full of reiterations of it, couched in seventeenth- century and Platon- istic language. "As for axiomatical truths," says Cudworth, for example, " in which something is affirmed or denied, as these are not all passions from bodies without us (for what local motions could impress this common notion upon our minds, that things which agree in one third, agree amongst themselves, or any other ?) ; so neither are these things only gathered by induction from repeated sensations. . . . Thus Aristotle ingeniously: 'It is evident that there is no knowledge (of the uni- versal theorems of geometry) by sense. For if we could perceive by sense that the three angles of a triangle were equal to two right ; yet should we not rest satisfied in this, as having therefore a suflBcient knowledge hereof; but would seek further after a demonstration of it; sense reaching only to singu- lars, but knowledge to universals.' When from the universal idea of a triangle, which is neither here nor there nor anywhere without our mind, but yet hath an intelhgible entity, we see a plain necessity, that its three angles must be equal to two right, then do we know the truth of this universal theorem, and not before: as also we understand that every singular triangle (so far as it is true) hath this property in it, wherefore our knowledge of this, «76 KANT AND THE PLATONISTS and other like truths, is not derived from singulars, nor do we arrive to them by way of ascent from singulars to universals ; but, on the contrary, hav- ing first found them in the universals, we afterward descending apply them to singulars: so that our knowledge here is not after singular bodies, and secondarily or derivatively from them, but in order of nature before them, and proleptical to them." ^ Among the arguments in Kant's "Transcendental Esthetic" by which he seeks to establish the apri- ority of the Vorstellungen of space and time, the only one that can be considered entirely unequiv- ocal and important, the one which he himself, in the Second Edition, erects into a separate section of his reasoning under the name of the " Transcen- dental Exposition," is that based upon the alleged existence of indubitable and clearly a priori judg- ments in the mathematical sciences and in the general axioms concerning the time-relations of phenomena. Similarly the Enghsh Platonists habitually rest their case for the reality of a priori mental elements chiefly upon the certainty of the fundamental propositions of mathematics — propo- sitions which, because they are universal, could not be justified upon the basis of experience. This habit in the Cambridge men is perhaps suflSciently exemplified by the last citation from Cudworth; many more examples could, however, be drawn from that writer and from More.

LOVEJOY 277 argumentative basis for the apriorism of these seventeenth-century epistemologists was thus identical with the only serious argumentative basis for the apriorism of Kant's "Transcendental ^Esthetic. " It is, of course, true that these English Platonists made no such definite and methodical attempt to discriminate and precisely enumerate the several a priori elements in knowledge, as did the peculiarly systematic and taxonomic mind of Kant. Cud- worth and his school often wTite as if all sorts of miscellaneous general concepts might be supposed, like the original Platonic Ideas, to exist in the in- tellect a priori. This they certainly did not really mean to affirm ; but they undeniably left the ques- tion concerning the exact character and limits of the a priori as an unsettled problem for their suc- cessors to deal with. Kant must be said to have made an honest, though a far from successful, effort to grapple with this problem. But in doing so he was only correcting and filling in the details of the general epistemological scheme which he shared in common with his English rationalistic predeces- sors ; he was not discovering a new and revolu- tionary philosophical principle. And there are numerous indications in the work of seventeenth- century Enghsh writers that they primarily meant by their " proleptical " or a priori notions those relational ideas or categories which enter into every presentation of objects and make possible the unity 278 KANT AND THE PLATONISTS and interconnectedness of rational experience; and there are occasional rudimentary and tentative attempts at an enumeration of these categories. Thus Henry More : ^ " Besides this, there are a multitude of relative notions or ideas in the mind of man, as well mathematical as logical, which if we prove cannot be the impresses of any material object from without, it will necessarily follow that they are from the soul herself within, and are the natural furniture of human understanding. Such are these: Cause, Effect, Whole and Part, Like and Unhke, Proportion and Analogy, Equality and Inequality, Symmetry and Asymmetry, and the hke ; all which relative ideas I shall easily prove to be no material impresses from without upon the soul, but her own active conception proceeding from herself whilst she takes notice of external ob- jects."* Kant's systematic analysis of the a priori faculties of the mind seems to have been still more closely foreshadowed in the *' Organum Vetus et Novum" (1677) and the "Essay upon Reason and the Nature of Spirits " (1694) of Richard Burthogge, an Oxford man. But, unhappily, neither of these works of this noteworthy English philosopher ap- pears to be available anywhere in the city of New York; and I am dependent for information con- cerning them upon M. Lyon's invaluable study. If there be any reader of this paper not acquainted with M. Lyon's book, I can only refer him to it for * "Antidote against Atheism," 1655, p. 22. ARTHUR O. LOVEJOY 279 a too brief account of a system exhibiting, in its general outlines, a singular degree of resemblance to the theoretical philosophy of Kant. But I can- not refrain from including in the present compila- tion of English anticipations of Kant a passage of Burthogge's expressing very precisely the peculiar type of the Kantian idealism — an idealism pri- marily based upon, and hmited in its bearings by, the epistemological theory of a priori mental ele- ments. It is necessary to turn this back into English as well as may be from M. Lyon's French rendering.^ "For us men," says Burthogge," things are noth- ing save in so far as they are known by us, and they are known by us only as they exist in the sense or imagination or thought; in a word, as they exist in our faculties. . . . Each faculty takes a part, though not an exclusive part, in the produc- tion of its immediate object; as the eye produces colors and is said to see, as the ear produces sounds and the imagination images, so the under- standing produces the ideas or conceptions under which it apprehends and beholds things. So that all the immediate objects of human thought are entia cogitationisy or appearances only ; they being not properly and (if I may be allowed to use a school- term) formally in the things themselves . . . but only in the faculties of the intellect." This is pure Kantian (as distinguished from Berke- ' " L'Idealisme en Angleterre au X\^^« si^cle," pp. 75, 76. 280 KANT AND THE PLATONISTS leyan) idealism ; and Burthogge holds fast as ten- aciously as Kant to the aflfirmation of the real existence of things-in- themselves behind these mentally apperceived and subjectively determined objects of experience. He does so, also, as M. Lyon points out, for a like reason, and with a like inconsequence; he feels the necessity of assigning some extra-mental cause for the concrete, contin- gent, empirical element in the content of sensation. It is natural to inquire, at this point, whether the philosopher of Konigsberg can have known and in any degree have been influenced by these EngHsh precursors. That Kant should not have read Cudworth would certainly have been singu- lar. A Latin translation of the "True Intellectual System'* by J. L. Mosheim, a professor and even- tually chancellor of the University of Gottingen, was pubHshed at Jena in 1733, and a second edi- tion at Leyden forty years later ; to the latter pubh- cation attention was called in Nicolai's " Allgemeine deutsche Bibliothek" of the same year. But, as I have said, Kant was capable of ignoring to an ex- traordinary degree — or, it may be, of forgetting — a large part of the philosophical literature of his time. If he had read and remembered Cudworth, or any other writer of the same school, he could hardly have flattered himself so complacently as he did upon the entire novelty of his " Copernican revolution." ARTHUR O. LOVEJOY 281 II The doctrine of the ideahty of the world of objects in space and time rests, in Kant's system, upon two supports of dissimilar character and un- equal strength. In the " Transcendental Esthetic " it is a direct inference from the theory that our no- tions of space and time constitute pure percepts of which the mind is in possession a priori; from the epistemological affirmation of the apriority of our ideas of these two elements of the world of our sensible experience, is immediately deduced the metaphysical negation of the extra- mental reahty of that world, so far, at least, as its spatial and temporal contents are concerned. But even sup- posing the arguments offered for the existence of space and time as a priori percepts to be conclusive — a point which it would be out of place to discuss here — the transition from apriority to ideahty is manifestly something less than coercive. For the transition gets its sole sanction from the law of parsimony; which can hardly be regarded as an absolutely necessary law of thought. Why should not space or time be both an idea with which our mind is furnished a priori, and also a real charac- ter of the objective universe of Ding e- an- sick? In the "iEsthetic" Kant certainly is constantly guilty of the paralogism of translating the proposition, "Space is the subjective form of the perception 282 KANT AND THE PLATONISTS of phenomena of the external senses" into the proposition "Space is nothing but the subjective form of the perception of the phenomena of the external senses." To assert dogmatically the ex- istence of space on both sides of the Kantian an- tithesis of thought and thing would perhaps be to multiply entities beyond necessity. But the proof that such an hypothesis is not necessary is not equivalent to a proof that it is false or impossible or absurd. After all of Kant's reasoning upon this subject in the earlier part of the ** Kritik" one is left with a fairly open option between two perfectly conceivable hypotheses, namely : Space and time are exclusively subjective forms; or, Space and time are at once subjective forms and objective realities. The latter hypothesis is the less simple of the two, it is less in conformity with the maxim known as "Ockham's razor"; but on the other hand, it seems more natural and more congen- ial to the human intellect. Consequently, though admitting the validity of every one of Kant's reasonings in the "Transcendental ^Esthetic, " a fair observer of the situation could hardly say more than that, at the end of that part of the dis- cussion, the conflict between critical idealism and physical realism had issued in a draw. But in the "Transcendental Antithetic" Kant brings forward an argument for his sort of idealism that has much greater pretensions to compulsive- ness and conclusiveness. In the first and second ARTHUR O. LOVEJOY 283 antinomies and the "critical solution of the con- flict of reason with itself" in those cosmological problems, he undertakes to show that the assertion of the objective reahty of the spatial and temporal world is, not simply superfluous, but absurd and self-contradictory. For — as the familiar argument runs — so long as we think of space and time as really existing things we can, with perfect logic, prove either to be both infinite and finite in extent, both infinitely divided and incapable of infinite division. For the realist there is no escape from this paradox. Only transcendental idealism can make clear at once the origin and the solution of this apparent self-contradiction and self- stultifi- cation of the human understanding. " If we regard the two statements that the world is infinite in ex- tension, and that the world is finite in extension, as contradictory opposites, we assume that the world is a thing in itself;" and from this assumption the whole absurdity arises. "But if we remove this supposition, or transcendental illusion, and deny that the world is a thing in itself, then the con- tradictory opposition of the two statements becomes purely dialectical, and as the world does not exist by itself (independently of the regressive series of my representations), it exists neither as a whole by itself infinite^ nor as a whole bij itselj finite.** In short, "the antinomy of pure reason with regard to its cosmological ideas is removed by showing that it is ... an illusion produced by our apply- 284 KANT AND THE PLATONISTS ing the idea of absolute totality, which exists only as a condition of things by themselves, to phenom- ena, which exist in our representation only. . . . We may, however, derive from that antinomy a true . . . advantage, namely, by proving through it indirectly the transcendental ideality of phenom- ena, in case anyone should not have been satisfied by the direct proof given in the 'Transcendental .Esthetic. * The proof would consist in the following dilemma : If the world is a whole existing by itself, it is either finite or infinite. Now the former as well as the latter proposition is false, as has been shown by the proofs given in the antithesis on one and in the thesis on the other side. It is false, there- fore, that the world is a whole existing by itself. Hence it follows that phenomena uberhaupt are nothing outside our representations." This argu- ment Kant — who never recognized the obvious limitations of the arguments in the " Transcendental ^Esthetic" — advances as a subsidiary rather than as the main proof for his transcendental idealism. But it is apparent, from what has already been said, that it is really the only argument that has any claim to be regarded as commensurate with the thing to be proven. The other leg of Kant's reasoning, so to say, is visibly too short to reach up to the con- clusion that it is designed to support. Now, just this argument from the antinomies respecting the infinity and infinite divisibihty of space to an ideaHstic conclusion, had been clearly. ARTHUR O. LOVEJOY 285 and a ^ood deal more simply, set forth by Arthur Collier in his "Clavis Universalis" (1713). As that remarkable work of the earUest ^ Enghsh ideahst is less famiUar and less accessible than it should be, I reproduce with some fulness the passages in which Colher anticipates Kant.' The "third argument" in the "Clavis" for the ideahty of the external world is as follows: "An external world whose extension is absolute, that is, not relatively depending on any faculty of percep- tion, has (in my opinion) such a repugnancy in its extension as actually destroys the being of the subject- world. The repugnancy is this, that it is, or must be, both finite and infinite. Accordingly, then, I argue thus : That w'hich is both finite and infinite in extent is absolutely non-existent, or there is, or can be, no such world ; or thus, an ex- • Berkeley's "Principles of Human Knowledge" was published in 1710. But an earlier draft of Collier's argument has been found, dating from 1708 (see LyesUe Stephen, s. v., in "Dictionary of National Biography"); and Collier himself speaks of ha\'ing waited ten years before publishing his new theories. There appears to be no evidence of Berkeley's having hit upon his doctrine before 170.5. If our histories of philosophy were as solicitous to be historical as they are to be philosophical, the name of Colher would be coupled with that of Berkeley as constantly and closely as is the name of Leibniz with that of Newton in the history of mathematics, the name of Wallace with that of Darwin in the history of biologj', the name of Adams with that of Leverrier in the history of planetary astronomy. As a matter of fact, in Windelband's " History of Philosophy " the date of Collier's book is given wrongly (EngUsh tr., p. 471), and the simultaneity of the two "discoveries" of idealism is not pointed out ; in Ueberweg Colher is incorrectly said to have been influenced by Berkeley; and in Hdtlding there is to be found no mention of Collier at all. * Citations are from the edition of the " Clavis Universalis " in Parr's *' Metaphysical Tracts by English Philosophers of the Eighteenth Centurj-," London, 1837. 286 KANT AND THE PLATONISTS tent or expansion which is both finite and infinite is neither finite nor infinite, that is, is no expansion at all. But this is the case of an external expansion, ergo, there is, or can be, no such expansion." Collier then dilates upon the self-evidence of the two essential premises of this reasoning, and con- tinues: "As to the form and manner of this argu- ment, it has first evidently this to plead for itself, that there is nothing in its conclusion but what is in the premises ; which shews it to be no fallacy but a just and legal argument. And also this, secondly, that it is exactly parallel with several arguments which I could name, allowed by all to be good and perfectly demonstrative. As for in- stance, suppose a man should advance the notion of a triangular square. Or suppose two persons contending about the attributes of this strange idea : one arguing from the idea of triangle, that it has but three angles ; and the other contending that it must have four, from the idea of a square; what could any reasonable stander-by conclude from this, but that the thing they are disputing about is nothing at all, even an impossibility or contradic- tion? Nay, the disputants themselves must needs close in with this manner of arguing, and that on two accounts. "First, in that this manner of arguing accom- modates the difference between them, and salves the honor of both. For by this, both appear to be in the right in the precise points they are con- ARTHUR O. LOVEJOY 287 tending for; and wrong only in something which they are both equally concerned for, viz., the sup- position of the being of a triangular square, which is the thing supposed by consent between them. But chiefly, secondly, in that tl^.e person who argues in this manner must be compelled to have the law of reason on his side, and may compel them, on their own principles, to assent to his conclusion. This is done by granting to each party his point, namely, that a triangular square is both triangular and quadrangular. This done, they have nothing to do but to answer each other's arguments, which it is here supposed they cannot do. By this, there- fore, each grants the other to be in the right. So that for a stander-by to grant both to be in the right is, in this case, a demonstration that they are both in the wrong; or in other words, that the thing they are disputing about is nothing at all. I have mentioned this possible, rather than any actual^ instance of this kind, because I would give an in- stance wherein I may be sure to have every one on my side. For certainly no one can doubt whether this be a good argument or not : "A figure which is both triangular and quad- rangular is not at all. But this is the case of a triangular square. Ergo, there is no such figure." Precisely parallel to this, then. Collier observes, is the argument concerning the external world, as thus : 288 KANT AND THE PLATONISTS "A world which is both finite and infinite is not at all. But this is the case of an external world. Ergo, there is no such world." Similar is Collier's "fourth argument." "From the maximum I come to the minimum naturale; or to the question about the divisibility of matter, quantity, or extension. And here I afiirm in like manner as before, that external matter is both finitely and infinitely divisible; and, consequently, that there is no such thing as external matter.'* This idealism of Collier's — all of the arguments for which are more to the point than any of Kant's except those which the " Kritik der reinen Vernunf t " has in common with the " Clavis Universalis " — is, he is careful to point out, not to be understood as a denial of the empirical reality or even of the phe- nomenal externality of that general and collective object of sense, a natural world. "Let the mean- est of my readers be my witness, that I have been so far from doubting of anything of this that I have even contended on all occasions that nothing is, or can be, more evident than the existence of bodies, or of a sensible world. . . . Not the existence but the extra- existence of the sensible world is the point I have been arguing against. And that, not a natural, supposed to be a sensible, but an external world, as such, is impossible." ^ ^ M. Lyon has pointed out (more briefly) the similarity between these sec- tions of the " Clavis Universalis " and the Kantian antinomies (op. cit., pp. 262, 263) ; but by others the point appears to have been usually ignored. ARTHUR O. LOVEJOY 289 The same general line of argument in behalf of ideahsm was simultaneously occurring to the mind of Berkeley ; it is by him expressed in §§ 47, 123- 134 of the " Principles of Human Knowledge." But Berkeley is far from bringing out the essential point and the precise logical character of the argument from the antinomies so clearly and unmistakably as does Collier; and the form of his reasoning resembles that of Kant much less closely. The para- doxes about infinite extension and infinite divisi- bihty are, in themselves, of course, a very ancient heritage of European philosophy, going back at all events to Zeno of Elea. But Collier appears to have been the first modern to whom it occurred to use them as a decisive argument against physical real- ism in precisely the Kantian manner. The ques- tion here again naturally suggests itself, whether Kant can have consciously or unconsciously de- rived the suggestion of his own antinomic rea- soning for the transcendental ideality of time and space from the English idealist. That Kant should have been acquainted with the '* Clavis Universalis " is by no means impossible, since a German trans- lation of it, together with Berkeley's " Dialogues," was brought out in 1756 by C. E. Eschenbach, a physician of contemporary celebrity, then pro- fessor of mathematics, and later of anatomy, at Rostock. If Kant failed to improve this oppor- tunity — he had, of course, little or no English — to become better acquainted with the much-dis- 19 290 KANT AND THE PLATONISTS cussed reasonings of these English speculators, he certainly fell somewhat short of his professional obligations. But the probability is against his having received any influence or suggestion from Collier; for one thing, it apparently was not until the year 1769 that (in the words of Adickes^) *'the problem of the antinomies, and his solution of that problem, brought about the change in Kant's views concerning space and time." We have here, probably, not a case of borrowing, but merely one of anticipation.^ 1 In his " Kant-Studien, " p. 122. * Kant might also have learned these ideas nearer home. In the assertion of the ideality of space he had, of com-se, several precursors in Gennany. Leib- niz had explicitly denied the existence of space as a real thing — as anything more than a " confused " representation of the mere relation of co-existence between unextended entities. Maupertuis, President of the Berlin Academy of Sciences, had maintained (in his Lettres, before 1752, Grerman translation, 1753) that " ritendve n'eat rien de plus qu'un phSnomme " ; and before the middle of the century the doctrine had become so much of a commonplace in Germany that Euler thought it necessary to devote one of his communi- cations to the Academy to the refutation of those metaphysicians who asserted that " les idAes de I'espace et du temps n'ont aucune rialiU " and that these ideas "n'existent que dans noire entendement" (Hist, de I' Acad. Roy. des Sciences, Berlin, 1748, pp. 324-333). But the reader of Kant alone would be likely to suppose this doctrine to be a peculiar and original discovery of the Konigsberger himself. Yet even in the antinomic argxmient for it he had German as well as English predecessors — though none come so close as Collier to Kant's own way of putting it. Leibniz had repeatedly urged that the only escape from the difficulties about infinite divisibility lay in the recognition of the phenomenality of space ; and Maupertuis had, as one evi- dence of the truth of his contention, pointed to " the great embarrassments into which we fall, when we attempt to carry extension out to infinity, or to decompose it into its ultimate elements." ARTHUR O. LOVEJOY 291 III It is well known that out of the conceptions and the dialectic implicit in Kant's theory of knowledge there was presently evolved a new type of specula- tive metaphysics and theology, which, in several forms, has had especial vogue and influence in England and America. Its most general and dis- tinguishing characteristic is that it finds the basis for an idealistic and (more or less frankly) monistic rational theology directly in the nature and pre- suppositions of knowledge as such; it rests its ar- gument for the existence of God, or an Absolute Mind, exclusively upon epistemological considera- tions of the Kantian type. By a species of reason- ing a fortiori, it concludes that since, as Kant had insisted, the world of experience as a coherent sys- tem of rationally interrelated objects is possible for me only in so far as its content subsists and is categorized within the unity of my mind — which provides the synthetizing system of spatial, tem- poral, and other relations but is itself something more than a term of those relations — so the whole of reality, including all finite minds, can be con- ceived only as subsisting within the unity of a single, all- comprehending, self-determining, and com- pletely rational Eternal Mind or Absolute Experi- ence. Now, a mode of theological reasoning and a type of theological conclusion pretty closely analo- gous to this is characteristic of the philosophy of 292 KANT AND THE PLATONISTS the Cambridge and Oxford Platonists of the seven- teenth century. It appears, as it does in different English metaphysicians of the neo- Kantian school, with varying degrees of definiteness, with unequal degrees of frankness in regard to the monistic or pantheistic tendency of it, and with different ways of carrying through the one general sort of dialec- tic common to the whole group. It is, in fact, possible to find fairly exact (though, of course, relatively crude) counterparts to three distinguish- able varieties of latter-day Kantian metaphysics — the varieties, namely, represented by Green, Royce, and Bradley — in three of our Platonists, respec- tively, Cudworth, Norris, and CoHier. 1. Readers of Thomas Hill Green have gener- ally found his language concerning the precise ontological relations of the Eternal Consciousness to finite minds somewhat obscure and elusive ; but have found him clear, at all events, in insisting that even our human cognition directly presupposes, and that its possibility becomes fully conceivable only through, the mediation of an Eternal Conscious- ness in whose nature and whose knowledge we (just because we are capable of a mode of insight transcending the temporal and contingent flux of sense- presentations) somehow participate. Cud- worth seems to me to be clear and to be elusive upon substantially the same points. "Human knowledge and understanding itself," he says (re- suming the epistemological reasoning cited earlier ARTHUR O. LOVEJOY 293 in this paper), "is not the mere image and creature of singular bodies only; and so derivative and ectypal from them and in order of nature junior to them, but, as it were, hovering aloft over the cor- poreal universe, it is a thing independent upon sin- ular bodies, or proleptical to them, and in order of nature before them. But what account can we then possibly give of knowledge and understand- ing, their nature and original ? since there must be vot]t6v, that which is intelligible, in order of nature before i/6r)cn<;, or intellection. Certainly, no other than this, that the first original of knowledge is that of a perfect being, comprehending . . . the possibil- ities of all things; their ideas with their several re- lations to one another; all necessary and immutable truths. Here, therefore, is a knowledge before the world and all sensible things, that was archetypal and paradigmatical to the same. Of which one perfect mind and knowledge all other imperfect minds (being derived from it), have a certain parti- cipation.'' ^ "It is evident that there can be but one only original mind, or no more than one un- derstanding being self-existent; all other minds whatsoever partaking of one original mind; and being, as it were, stamped with the impression or signature of one and the same seal. From whence it Cometh to pass that all minds, in the several places and ages of the world, have ideas or notions of things exactly alike, and truths indivisibly the same. Truths are not multiplied by the diversity of ' Cudworth, op. cit., p. 406. 294 KANT AND THE PLATONISTS the minds that apprehend them; because they are all but ectypal participations of one and the same original mind and truth. As the same face may be reflected in several glasses ; and the image of the same sun may be in a thousand eyes at once behold- ing it; and one and the same voice may be in a thousand ears listening to it ; so when innumerable created minds have the same ideas of things, and understand the same truths, it is but one and the same eternal light that is reflected in them all (' that light which enlighteneth every man that com- eth into the world') ; or the same voice of that one everlasting Word, that is never silent, re- echoed by them. . . . We conclude therefore that from the nature of mind and knowledge it is demonstrable that there can be but one original and self-existent mind, or understanding being, from which all other minds were derived." ^ Recurrent, similarly, in the writings of the Cam- bridge school is the observation that this ultimate Knower, this archetypal and perfect Mind, must transcend the ordinary duahty of thought and thing, must be at once subject and object of thought, by existing for itself as its own object. This prin- ciple of Platonistic theology, which goes back to Plotinus, if not, indeed, to Aristotle, is, as everyone knows, another of the commonplaces of the philoso- phy of those recent English schools whose lineage is usually traced through Hegel back to Kant. * Cudworth, op. cit., pp. 415, 416. ARTHUR O. LOVEJOY 295 2. In the second part of a remarkable early work of Professor Royce's, " The Religious Aspect of Philosophy," there is set forth an interesting variant of the general neo-Kantian or epistemo- logical type of argument for the existence of God. This argument undertakes to show that the very admission of the distinction between truth and error in judgments — an admission to which even the most determined sceptic stands committed — directly implies the aflBrmation of the existence of an objective and eternal standard of truth to which all judgments by their very nature aim to conform ; and that this standard can be inteUigibly conceived only if it be represented as an all-knowing and eternal Mind, which possesses and perfectly ap- prehends at once the judgment and the "reahty,'* or the truth at which the judgment aims. The skeleton of an epistemological argument for theism which assuredly belongs to the same genus, though it is far removed from the dialectical subtlety and the felicitous expression of Professor Royce's rea- soning, is to be found in John Norris's "Meta- physical Essay towards the Demonstration of a God from the steady and immutable Nature of Truth "^ (1687). To Norris himself his hne of argument seemed an essentially new mode of proof. "Whether," he writes, "this procedure of mine be entirely new or no, 't is not possible (without ex- amining all the books in the world) absolutely to ' Contained in Norris's " Collection of Miscellanies, " edition of 1717, pp. 144-152. 296 KANT AND THE PLATONISTS determine. This much I believe I may venture to say, that *t is nowhere universally received, nor by any that I know of, industriously and profess- edly managed ; and that, lastly, 't is as new as the matter will now afford, and consequently as any man in reason ought to expect." The argument, somewhat condensed, runs thus: Knowledge is "truth of the subject," and presupposes "truth of the object"; without the latter "there can be no such thing as knowledge." Now, truth of the ob- ject, in the sense in which it is here used, consists in "certain habitudes or relations of things towards one another, whether affirmatively or negatively.' Of these relations, "some are steady, immutable that never were made by any understanding or will nor can ever be unmade or nuU'd by them. . . Now, 't is a proposition of necessary and eternal truth, that there must be ever such a thing as truth or that something must be true; for let it be af firmed or denied, truth thrusts in upon us either way. And so, secondly, there are many particular propositions of eternal and unchangeable verity, as in Logic, . . . Physics, . . . Metaphysics, . . . Mathematics. . . . These and such like are stand- ing and irrepealable truths, . . . and such as all intellectual operations do not make but presup- pose ; it being as much against the nature of under- standing to make that truth which it speculates, as 't is against the nature of the eye to create that light by which it sees." Now since the simple es- ARTHUR O. LOVEJOY 297 sences to which these eternal relations belong must, accordingly, somewhere and somehow exist, and in a corresponding eternal manner, and since they can be seen not to do so "in their natural subsist- ences, it follows that they must be eternal in their ideal subsistences or reaUties. For there are but two conceivable ways how anything may be sup- posed to subsist, either naturally or ideally, either out of all understanding or within some under- standing." So, "if the simple essences of things do exist eternally, but not out of all understand- ing, it remains that they must have their existence in some understanding. Without which, indeed, it is not possible to conceive how they should have any such existence." It follows, then, "that there is a mind or understanding eternally existing which is omniscient and . . . universally representative of all other beings" — which "can be no other than that eternal mind which we call God." Norris in concluding offers a distinction whereby he may obviate a certain difficulty in this reasoning — one that, as the ingenious reader will easily remark, at- taches, in a shghtly different form to more modern versions of the argument. "Whereas in the third section [of Norris's essay] it was asserted that the nature of truth is steady and immutable, and such as has no precarious existence or arbitrarious de- pendence upon any understanding whatever; and yet in the fifth section 't is affirmed that it owes its existence to some mind or other; lest one part of 298 KANT AND THE PLATONISTS this meditation be thought to clash against an- other, I thought it requisite to adjust this seem- ing contradiction. For the clearing of which we must be beholding to that distinction of a Platonic author, of the divine mind into vov? vo€p6<; and pov
